Many of the moments being shared feature snippets of Gomez's life we rarely get to see. These are some of the sweet tributes that her friends have been sharing so far.
Vanessa Hudgens wished her "hunny bear" happy birthday with a cute picture of the two of them.
Collins wished Gomez a happy birthday and posted a throwback to a blonde Selena moment that we'd nearly forgotten about. Such a cute look!
She also shared a bunch of pictures of the singer cuddling dogs, writing, "My favourite Selena is doglena." We'd have to agree.
Singer Raquelle Stevens shared a number of IG stories for her close friend. "Big day today!" she wrote, continuing in the next story, "Happy Birthday @selenagomez! A decade of friendship together, we've been through it all. I cherish all of our memories, and this past year was filled with so many great ones..."
Lopez, who Gomez shares a matching tattoo with, shared some very sweet candids and pictures of her and Gomez together.
Artist and photographer Petra Collins shared a few tributes to Gomez, including a sneak peek of an upcoming project. "I literally cannot wait for our next thing - top secret but I’m vvvvvvvvv excited," she wrote in an Instagram story.
Collins also shared some candids, again of Gomez chilling out, this time with a giant teddy bear. "It’s someone’s bday. Someone v special who is strong as hell and probably one of my favorite subjects ever. Hehe but seriously I love you like my lil sis even though ur older now."
