Shawn Mendes has a new reason to smile, and this time it has nothing to do with a new song or a concert stage. The Canadian singer is dating Brazilian actress Bruna Marquezine, and after months of keeping fans guessing, the couple finally made their relationship public in a very sweet way.
Mendes and Marquezine had been linked for months before either one openly addressed their romance. They were seen together in Brazil, later spotted in Los Angeles, and gradually became one of the celebrity couples that fans could not stop talking about.
The biggest confirmation came in August 2026, when Mendes publicly celebrated Marquezine’s 31st birthday on Instagram. His message was far more personal than a simple birthday wish. He called her his “baby,” said she had changed his life and ended the post by telling her that he loved her. E! News reported that Mendes also shared photos and videos connected to Marquezine’s work with children at a community center in Rio de Janeiro.
So, who exactly is Shawn Mendes’ girlfriend? Here is everything to know about Bruna Marquezine, her career, their relationship timeline and why the couple has attracted so much attention.
Who Is Shawn Mendes’ Girlfriend?
Shawn Mendes’ girlfriend is Bruna Marquezine, a Brazilian actress and model who has been working in entertainment since she was a child.
Born on August 4, 1995, Marquezine grew up in Brazil and started appearing on television at a very young age. Her early career included commercials and children’s television before she moved into more prominent acting roles.
Over the years, she became one of Brazil’s recognizable television stars, appearing in several popular productions. Her career eventually moved beyond Brazilian television and into international film.
For many American viewers, Marquezine is best known for playing Jenny Kord in the 2023 DC movie Blue Beetle. The role introduced her to a much wider international audience and showed that her career was not limited to Brazilian productions.
But Marquezine was already a major celebrity in Brazil long before she appeared in Blue Beetle. She had built a substantial following through years of acting work, fashion appearances and public projects.
E! News noted that Marquezine has also been selective about discussing her private life. That approach is interesting because she is now dating one of the world’s most recognizable young singers.
When Did Shawn Mendes and Bruna Marquezine Start Dating?
The exact moment Shawn Mendes and Bruna Marquezine became a couple has not been publicly confirmed.
Romance rumors began circulating in late 2025 after the pair were spotted together in Brazil. Their appearances did not immediately result in an official relationship announcement, but fans quickly started noticing that Mendes and Marquezine seemed to be spending more time together.
According to E! News, the two were first linked after being seen together in Brazil in December 2025. The sightings continued into the beginning of 2026, giving fans more reasons to believe there was something romantic happening between them.
Instead of rushing to confirm the rumors, the pair appeared to take a quieter approach.
That made the relationship even more interesting to fans.
Shawn Mendes and Bruna Marquezine’s Relationship Timeline
The romance between Mendes and Marquezine developed gradually in public, even though neither star initially wanted to put a label on it.
Late 2025: Romance Rumors Begin
The first major rumors appeared toward the end of 2025.
Mendes and Marquezine were spotted together in Brazil, where their interactions began attracting attention. They were reportedly seen spending time together during a period when Mendes was visiting the country.
At that point, there was no official confirmation that they were dating.
Still, the repeated sightings made it increasingly difficult for fans to ignore the possibility of a romance.
January 2026: Public Affection in Los Angeles
The relationship became much harder to dismiss in January 2026.
The couple were photographed together during a casual outing in Los Angeles, where they appeared affectionate while shopping at a grocery store.
According to E! News, the pair were seen hugging several times during the outing. Mendes and Marquezine kept their clothes casual, but their body language suggested they were comfortable with each other.
This was an important moment because it gave fans one of the clearest public signs yet that their relationship was more than friendship.
2026: More Time Together
As the year continued, Mendes and Marquezine were seen together in different settings.
They appeared to be comfortable balancing private time with occasional public outings. Their relationship was not constantly displayed online, which was consistent with Mendes’ own approach to his personal life.
The singer has previously spoken about how social media attention can have a negative effect on relationships. In a 2024 interview cited by E! News, Mendes explained that he had become stricter about keeping his romantic life away from social media because of the impact outside opinions could have.
That makes the couple’s eventual decision to go public even more significant.
August 2026: Shawn Mendes Makes the Relationship Official
The biggest moment came on August 4, 2026.
Marquezine turned 31, and Mendes used the occasion to publicly celebrate her on Instagram.
Rather than posting a simple birthday photograph, he shared a heartfelt message that made it clear she was much more than a rumored girlfriend.
Mendes called Marquezine his “baby” and wrote that she had truly changed his life. He also expressed how grateful he was for her before ending the message with “Eu te amo,” meaning “I love you” in Portuguese.
The post included footage connected to Marquezine’s visit to Casa Amarela Providência, a cultural center in Rio de Janeiro where she was volunteering with children.
For fans who had followed the couple’s story from the early rumors, this was the confirmation they had been waiting for.
Why Shawn Mendes’ Birthday Message Was So Important
Celebrity couples often become official through a carefully planned red carpet appearance or a social media photograph.
Mendes chose something more personal.
His birthday message focused heavily on Marquezine herself and the qualities he appreciates about her. He highlighted her kindness and the impact she had made on his life instead of simply showing off their relationship.
That detail stood out.
The singer also shared content related to her charitable work, which gave fans a glimpse into another side of their relationship. It suggested that his admiration for Marquezine goes beyond her career and public image.
E! News described the Instagram post as Mendes’ public confirmation of their relationship.
For someone who has previously preferred privacy when it comes to dating, the gesture was particularly meaningful.
Who Is Bruna Marquezine Outside Her Relationship With Shawn Mendes?
It is easy for the public to identify Marquezine simply as Shawn Mendes’ girlfriend, but that does not really tell her story.
She had already established a long career before meeting Mendes.
Marquezine started working in entertainment when she was a child. According to E! News, she appeared in commercials and on the Brazilian children’s program Gente Inocente at an early age. She later built a successful television career in Brazil.
Her transition into international entertainment came with Blue Beetle.
In the DC superhero film, she played Jenny Kord, a major character alongside Xolo Maridueña’s Jaime Reyes. The movie gave Marquezine a chance to introduce herself to audiences who may not have known her earlier Brazilian work.
That international exposure also helped establish her as a star in her own right.
Bruna Marquezine’s Previous Relationships
Before her relationship with Mendes, Marquezine was already familiar with intense media attention surrounding her personal life.
She had a high-profile, on-and-off relationship with Brazilian football star Neymar.
The two were linked between 2013 and 2018, making their romance one of the most closely followed celebrity relationships in Brazil during that period.
Marquezine later dated her Amor da Minha Vida costar João Guilherme. Their relationship became public in 2024, but the pair announced their split in early 2025, according to E! News.
Her history with other famous figures means she has experienced the pressure that can come with having a very public relationship.
That may help explain why she and Mendes initially chose to keep their romance relatively quiet.
Shawn Mendes’ Dating History
Mendes also has a very well-known romantic history.
His most famous relationship before Marquezine was with singer Camila Cabello.
The pair first became romantically involved in 2019 after years of friendship and musical collaboration. Their relationship became one of the biggest celebrity romances in pop music, especially after the success of their song Señorita.
Mendes and Cabello split in 2021 but briefly rekindled their romance in 2023 after being seen together at Coachella. Their second attempt did not last long.
Mendes was also linked to Sabrina Carpenter around that period, although their relationship was never confirmed in the same way as his romance with Cabello.
Before that, Mendes was connected to Hailey Bieber after they attended the 2018 Met Gala together. Mendes later described that situation as being more complicated than a traditional relationship.
His romance with Marquezine therefore represents another major chapter in his personal life.
Shawn Mendes and Bruna Marquezine Both Value Privacy
One of the most interesting things about this couple is how similar their attitudes toward privacy appear to be.
Mendes has openly discussed stepping away from social media when it comes to his relationships. He previously said that he does not want outside commentary to affect his romantic life.
Marquezine has also talked about learning to keep certain parts of her life private.
That makes their slow approach to going public understandable.
Instead of announcing their relationship immediately, they allowed people to notice their connection gradually. There were sightings, photographs and public appearances, but no immediate statement from either star.
Then Mendes finally decided to share something meaningful on his own terms.
Why Fans Are So Interested in Their Relationship
The interest in Mendes and Marquezine is partly because they come from different entertainment worlds.
Mendes is a Canadian singer who became internationally famous through songs such as Stitches, Treat You Better and There’s Nothing Holdin’ Me Back.
Marquezine is one of Brazil’s best-known actresses and has also developed an international profile through Blue Beetle.
Their relationship brings together two major fan bases.
There is also a natural curiosity around their international connection. Mendes has spent considerable time in Brazil, while Marquezine’s career has increasingly reached audiences outside her home country.
For fans, the romance feels like the meeting of two established stars rather than one celebrity simply becoming known through the other.
What Shawn Mendes’ Message Says About Their Relationship
The language Mendes used in his birthday tribute was probably the clearest indication yet of how seriously he feels about Marquezine.
Saying that someone has changed your life is a much stronger statement than simply calling them a girlfriend.
He also used Portuguese in the message, which added a personal touch and connected with Marquezine’s Brazilian background.
The fact that he posted videos connected to her community work was another thoughtful detail.
It gave the impression that he wanted people to see the person he knows, rather than simply presenting his famous girlfriend to the world.
That distinction matters, especially for two people who have both tried to maintain some boundaries around their private lives.
Are Shawn Mendes and Bruna Marquezine Still Together?
As of the latest available reports in 2026, Shawn Mendes and Bruna Marquezine are publicly together.
Their relationship was officially acknowledged by Mendes in August 2026, when he celebrated Marquezine’s birthday and expressed his love for her.
The couple had already been seen together several times before the Instagram post, including their affectionate Los Angeles outing in January.
For now, they appear to be enjoying their relationship while still keeping much of their everyday life away from the public.
There has been no indication that either star wants to turn their relationship into a constant social media spectacle.
Final Thoughts on Shawn Mendes’ Girlfriend
Shawn Mendes’ girlfriend, Bruna Marquezine, is much more than a famous singer’s new romantic partner.
She is an established Brazilian actress who started working as a child, built a major television career in Brazil and eventually made an international breakthrough with Blue Beetle.
Her relationship with Mendes appears to have developed quietly. Rumors began in late 2025, public affection became more noticeable in early 2026, and Mendes finally confirmed the romance in August when he shared an emotional birthday tribute for Marquezine.
The couple’s decision to take their time before going public fits with what both have said about privacy.
For Mendes, the relationship marks a new chapter after several highly publicized romances. For Marquezine, it is another high-profile relationship, but one that exists alongside a career she built long before becoming linked to the Canadian singer.
For now, fans will likely continue watching their public appearances and waiting to see what comes next. But one thing is no longer a mystery: Shawn Mendes and Bruna Marquezine are officially a couple, and Mendes seems very happy to let the world know it.
