Shawn Mendes has thanked his girlfriend for “truly changing” his life while going public with their relationship. The Stitches singer took to Instagram to wish Bruna Marquezine a happy 31st birthday, sharing a video of his other half walking into what appeared to be a surprise party. Alongside the videos, as well as a picture of Bruna, Shawn wrote: “Feliz aniversário [happy birthday] my baby“You are a light and a mãe [mother] in every room you walk into. Shawn’s relationship with Bruna was first reported last December (25) by the New York Post’s Page Six. The romance comes after Shawn’s previous public relationship with Señorita collaborator Camila Cabello, who he dated on and off from 2019 to 2023.
