Selena Gomez turned 20 yesterday! The actress/singer/number one Belieber seems to have crammed so much in, in such a short space of time. She's been a red carpet regular since the tender age of 14 so she knows her stuff when it comes to getting primped and preened for a big event and she's always one to watch because she loves a good ol' style switcheroo. From bold lips to 1970s disco curls, the Disney darling pulls off every look with ease. Here's wishing you the best birthday, Selena!
