Selena: It's 'Surreal' To Share Royal Birthday

Selena Gomez turned the big 2-1 today, a momentous occasion shared by the arrival of Prince William and Kate Middleton's royal baby. 
And, as it turns out, the singer/actress is just as obsessed with the news of the day as the rest of the world.
"It's surreal," gushed Gomez of sharing a star sign with the Duke and Duchess of Cambridge's first-born son. "We'll have joint birthday parties or something!"
And speaking of birthday parties, the 21-year-old star marked her passage into adulthood with a sexy new party video to accompany the track Birthday from her new album Stars Dance, in stores tomorrow.
