See Selena Gomez's Sexiest Minidress Moments; We salute the Birthday Girl's Fashion Evolution

Selena Gomez turned 20 yesteday! The singer, actress, and all-around cutie-patootie is no stranger to hitting the red carpet (as far as we're concerned, Justin Bieber is her arm candy). Between her sexy skirts, minidresses, and short-shorts, Selena Gomez has a serious penchant for showing off her pins — and we're currently taking bets that she'll stick to her style signature at today's Teen Choice Awards. She manages to show skin without being OTT and always looks sophisticated and age-appropriate. In honour of Selena's 20th birthday, we're celebrating with a collection of her best mini moments.
