Justin didn't accompany Selena to the party. So who was her special guest? It was someone else who loves her a lot - her mom!
Mandy really enjoyed going to the party with her daughter and Selena was having a good time, joking with lots of guests. Check out this Foto she uploaded to her Twitter with Lily Collins. Instead of daintily picking at canapes, Sel and Lily chose to gobble up some In 'N Out hamburgers.
Of course, after the party Selena got right back to her busy life. She hopped on a flight to Florida to meet up with Vanessa Hudgens and Ashley Tisdale. They're going to start shooting Spring Breakers in just a few days!
