Happy birthday, Kiernan Shipka! The rising actress turns 15 today. She was only six when she began playing Sally Draper on Mad Men, a role that has earned her a Screen Actors Guild Award for Outstanding Performance in 2008 and 2009, along with the rest of the cast. As Don and Betty Draper's eldest child (we're jealous she gets to spend so much time with Jon Hamm!), her character has become increasingly sassy, but off-screen, Shipka is quite the opposite. Compared to other teen stars, she's mature, poised, and already a red carpet stunner. The budding fashionista was one of Time's 25 Most Influential Teens of 2014 and was honored at People's Ones to Watch Party. Here's to another stylish year ahead!
