Happy birthday to Selena Gomez! The 'Come & Get It' songstress turns 21 years old today, and she's celebrating the only way a pop star knows how... by releasing a wild party video for her track 'Birthday.'

Not only is it a brand-spankin' new video, but it also features the song 'Birthday' from her album 'Stars Dance,' which comes out tomorrow (July 23). Happy birthday to us!

The fun and frantic video is the perfect visual for the youthful party anthem. Though the line, "Blow your dreams away with me," gives the feeling of a drug-addled rager as opposed to an innocent dance soiree.

Being 21 is fun, Sel, but be wary if any creeps come up to you at a club tonight and ask you to "blow away your night" with them.
