Shawn Mendes has officially made his relationship with girlfriend Bruna Marquezine Instagram official.
In an Instagram post shared on Tuesday (Aug. 4), the pop star featured the Brazilian actress on his main feed for the first time as he celebrated her 31st birthday.
The birthday tribute included photos and videos of the couple spending time at Casa Amarela Providencia, a cultural center located in Rio de Janeiro.
“Feliz aniversário my baby [wing and heart emojis],” Mendes, 27, wrote in the caption. “You are a light and a mãe in every room you walk into. Not to be tooooo sappy but you’ve truly changed my life and I am so so grateful for you. Eu te amo muito muito muitoo!!! We all do amor…”
According to People, speculation about the pair’s romance first emerged in 2025. The two were spotted together at Dua Lipa’s concert in São Paulo in November 2025 before ringing in the New Year together in Brazil’s Alagoas state.
Born and raised in Duque de Caxias near Rio de Janeiro, Marquezine began her career as a child performer, appearing in commercials at age 5 and securing roles in Brazilian soap operas at age 6, according to Elle. In 2023, she made her Hollywood debut in the film Blue Beetle.
