Who Is Shawn Mendes Dating? His Girlfriend Explained

The Short Answer

Shawn Mendes is dating Bruna Marquezine. The 28-year-old Canadian singer hard-launched the relationship on August 4, 2026, posting a heartfelt birthday tribute to the Brazilian actress on Instagram for her 31st birthday. Writing partly in Portuguese, Mendes called her his baby, said she had changed his life, and declared his love, ending months of speculation that began when the two were first spotted together in December 2025.

Marquezine, a major star in Brazil known for telenovelas and films, had been romantically linked to Mendes after TMZ published photos of the pair kissing on a Brazilian beach in early 2026, followed by sightings at a grocery store and in both Brazil and the United States. The August Instagram post, featuring videos of the couple celebrating her birthday in Rio de Janeiro, confirmed what fans had suspected for eight months. Mendes was previously in the high-profile relationship with Camila Cabello (2019-2021, with a brief reunion in 2023) and was linked to Sabrina Carpenter.

The Instagram Hard Launch

The confirmation came on August 4, 2026, Marquezine's 31st birthday. Mendes shared a carousel of videos and photos from her celebration at Casa Amarela Providencia in Rio de Janeiro, where she marked the day with a large group of children. His caption, written in a mix of English and Portuguese, read in part: Feliz aniversario my baby, calling her a light in every room and saying she had truly changed his life, closing with Eu te amo muito muito muitoo (I love you so, so, so much).

The post was immediately picked up by People and entertainment outlets worldwide, and fans celebrated the hard launch after months of detective work. Mendes also shared moments from the day on his Instagram Stories, including a photo of Marquezine hiding her face behind her dog. The public declaration marked a new level of openness for Mendes, who had kept previous relationships relatively guarded in their early stages.

The birthday post's Portuguese passages delighted Brazilian fans, who claimed Mendes as an honorary Brazilian, and the couple's Rio celebration, surrounded by children at a charity-adjacent venue, projected warmth rather than glamour. It was a hard launch with heart: less red carpet, more real life.

The August 2026 hard launch, a carousel of affectionate photos, ended weeks of speculation that began with concert sightings. Fans noted the timing: both artists between major projects, free to enjoy a relationship without promotional machinery.

Relationship Timeline

Romance rumors began in December 2025, when Mendes and Marquezine were first spotted spending time together. In early 2026, TMZ published photographs of the two kissing on a Brazilian beach, and subsequent sightings showed them hugging at a grocery store and traveling between Brazil and the US. Neither confirmed the relationship at the time, but the pattern of joint appearances told its own story.

Through the spring and summer of 2026, they were seen together with increasing frequency, and by August, Mendes decided to make it official. The timeline, roughly eight months from first rumors to hard launch, mirrors the modern celebrity playbook: soft-launch through paparazzi sightings, then a definitive social media confirmation. As of the latest reports, the relationship is going strong, with Mendes making clear he is not single.

Before the confirmation, fan detectives had tracked the relationship through Instagram likes, matching locations and paparazzi shots, a modern courtship conducted half in public. The eight-month soft launch, from December rumors to August confirmation, is now a case study in how celebrities stage-manage revelation in the social media age.

Their 2026 festival summer, spotted together at multiple European events, built the narrative before the Instagram confirmation. Each sighting, hand-holding here, a shared laugh there, was documented by fan accounts within minutes.

Who Is Bruna Marquezine?

Bruna Marquezine, born Bruna Reis Maia on August 4, 1995, in Duque de Caxias, Brazil, is one of Brazil's most famous actresses. She began acting as a child and became a telenovela star with roles in productions like Em Familia and I Love Paraisopolis, later transitioning to film, including the DC movie Blue Beetle (2023), where she played Jenny Kord.

With tens of millions of Instagram followers, she is a major fashion and beauty influencer in Latin America and has walked international red carpets. Before Mendes, she was famously in a long-term on-and-off relationship with Brazilian soccer star Neymar. Her pairing with Mendes unites two of the biggest young fanbases in the Americas.

Marquezine's Neymar history, a years-long on-off romance with Brazil's biggest soccer star, made her tabloid royalty long before Mendes. The contrast between the two relationships, soccer bad boy versus sensitive pop star, is a favorite Brazilian media narrative.

Past Relationships: Camila and Sabrina

Mendes's most famous relationship was with Camila Cabello, his Senorita collaborator. They dated from 2019 to 2021, becoming one of pop's defining couples, announced their split in a joint statement, and then briefly reunited in 2023 before parting again. The on-off dynamic kept fans invested for years.

In 2023 he was also linked to Sabrina Carpenter, though neither confirmed a relationship, and to Dr. Jocelyne Miranda. The Cabello chapter, with its chart-topping duet and joint interviews, remains the relationship most associated with Mendes, making the Marquezine hard launch his first fully confirmed romance since.

The Cabello reunion at Coachella 2023, a kiss that broke the internet, lasted only months but reminded everyone of the pairing's nuclear chemistry. Both artists have since described the reunion as closure, a final chapter that allowed them to move on cleanly.

Who Is Shawn Mendes?

Shawn Peter Raul Mendes, born August 8, 1998, in Pickering, Ontario, Canada, rose to fame posting song covers on Vine as a teenager before signing with Island Records. His hits Stitches, Treat You Better, Mercy and Senorita (with Cabello) made him one of the biggest pop stars of the late 2010s, with multiple number-one albums.

In 2022 he canceled a world tour to focus on his mental health, a decision widely praised for its candor, and returned with new music exploring more personal themes. He has been open about anxiety and the pressures of fame, and his 2026 hard launch of the Marquezine relationship suggests a new chapter of openness in his personal life.

His 2024 self-titled album Shawn marked his most personal work, written in the aftermath of the tour cancellation and his public reflections on sexuality and identity. Critics praised its folk-inflected honesty, and the album's reception suggested fans had grown with him from teen idol to thoughtful adult artist.

Mendes's 2024 album Shawn, a folk-influenced departure, was his most personal work, addressing his breakup, mental health and search for meaning. The record's intimacy set the template for his current, more grounded public persona.

Mendes on Mental Health and Fame

Mendes's openness about mental health has defined his recent years. His 2022 decision to cancel a massive world tour to prioritize his wellbeing was a watershed moment for pop-star candor, and his subsequent music explored anxiety, identity and the cost of fame with unusual directness. He has spoken about the pressure of growing up in public and the therapy and self-work that helped him rebuild.

That journey contextualizes the Marquezine relationship: friends describe a more grounded Mendes, clearer about what he wants and less willing to perform his personal life for public consumption. The hard launch, on his own terms and in his own words, reflects the same authenticity he has brought to his mental health advocacy.
