Shawn Mendes has gone Instagram official with his girlfriend.

The singer celebrated his girlfriend Bruna Marquezine's birthday with a loving post.

“Feliz aniversário my baby,” he wrote in a message to the Brazilian model/actress. “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.”

The post featured video of the two visiting Rio de Janeiro’s Casa Amarela Providência, a cultural center for local children.

Shawn concluded the post by writing in Bruna’s native Portuguese, “Eu te amo muito muito muitoo,” which translates to “I love you so, so, so much.”

Shawn and Bruna reportedly began dating in December. Shawn previously dated Camila Cabello from 2019 to 2023.
