Happy Birthday, Selena Gomez! Justin Bieber's Ladylove Turns 20

Former Wizards of Waverly Place star steps away from her teens after one major career-boosting year

Selena Gomez is all grown up.

The singer-actress who celebrates her 20^th birthday today, has had quite the year leading up to her big 2-0, canoodling around the globe with her boyfriend Justin Bieber, launching her own perfume, and starring in the upcoming flick Spring Breakers.

And let us not forget the release of her addictive hit, "Love You Like a Love Song," of which her Spring Breakers co-star James Franco is clearly a fan.

Dubbed "Hollywood's New It Girl," by Elle last month, the former Wizards of Waverly Place starlet is gearing up to take Tinseltown by storm…and we can't wait to see what's in store. 

Perhaps, for starters, an awesome birthday surprise from the Biebs?
