Selena Gomez Style Pictures

Selena Gomez is turning 20! The singer, actress, and all-around style setter 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 gams — and has been racking up leg-baring moments left and right. She manages to show skin without being over-the-top and always looks sophisticated and age-appropriate. In honor of Selena's 20th birthday this Sunday, we're celebrating with a collection of her best mini moments.
