On Tuesday, August 4, the Treat You Better hitmaker marked his girlfriend's 31st birthday with an emotional Instagram tribute. 

"Feliz aniversário my baby," he captioned the sweet post.

"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 27-year-old singer penned in his heartfelt post.


He then penned a sweet message in Portuguese, adding, "Eu te amo muito muito muitoo [I love you so, so, so much]."

The first video included the actress and model being greeted by a room of excited children as they ran to hug her. Another video included Marquezine singing and dancing as the crowd of children seemingly sang "Happy Birthday" to her.

Mendes added a video of himself smiling and posing with two children at Casa Amarela Providencia. The Instagram post concluded with a snap of Marquezine posing for the camera, as she held her dog right in front of her smile.
