Shawn Mendes publicly confirmed his relationship with Brazilian actress and model Bruna Marquezine with a birthday-post on Instagram that included videos and a photo featuring Bruna and children from a Rio de Janeiro community center.

In the caption, Mendes wrote in Portuguese, 'Eu te amo muito muito muitoo,' signaling deep affection.

The reveal sits within a broader trend of celebrity couples publicly launching relationships on Instagram, reflecting contemporary media interest in their coupling.

The couple’s public appearances are framed within Mendes’ ongoing environmental and public-life engagements, including prior high-profile events like the Earthshot Prize Awards in Rio de Janeiro in late 2025.

Coverage highlights other celebrity couples who have used Instagram to announce relationships, illustrating a current reporting trend.

Bruna Marquezine began acting at a young age and has built a substantial career with roles in telenovelas and film, expanding into modeling and production.

Marquezine, born in 1995 in Brazil, rose to stardom early, later appearing in projects including The Flash (auditioned) and Blue Beetle as Jenny Kord, and pursuing international roles.

Marquezine left TV Globo to seek broader opportunities, balancing acting with modeling and production work.

Her career spans work from child acting in Globo to major novelas and later projects across film and production.

The term 'hard launch' signals a formal public confirmation of their romantic involvement.

Mendes has typically kept his private life private and has avoided social media, making this public confirmation notable.

Mendes is a Canadian singer-songwriter known for hits like Stitches and Senorita, who rose to fame via Vine and has since been open about mental health and personal experiences in his music.
