The pop star, who turned 20 Sunday, was serenaded by the crowd of thousands (which included some of the most talented teen-friendly singers, including Taylor Swift) gathered at Los Angeles's Gibson Amphitheatre as she was presented with yet another birthday treat: sparkler-topped Sprinkles cupcakes. Of course the b-day sweetie shared with the audience!
"This is the best birthday present ever," she said after she was presented with her Teen Choice surf board.
Marking the milestone with her: boyfriend Justin Bieber, who was seated next to her in the front row and performed later in the show before receiving an award of his own – choice male artist.
Other winners included Ellen DeGeneres, the cast of The Vampire Diaries, Miley Cyrus, Ian Somerhalder, Taylor Swift, Zac Efron, Josh Hutcherson and One Direction.
