Selena Gomez at the People’s Choice Awards in L.A.

Well, haven’t you grown up? Disney star (the one who hasn’t seen the inside of a rehabilitation center yet) Selena Gomez was looking mature in a sophisticated printed dress by Irina Shabayeva at the People’s Choice Awards which was held in Los Angeles last night. This dress is simply sublime, and the perfect fit for Selena, who has been causing Bieber fans everywhere to sigh in sadness after she was caught locking lips with the Biebs himself on a yacht over the holidays.

Selena’s dress features a dazzling hemline which dramatically plummets to the back, leading up to a train which unfolds elegantly behind her. Selena has topped off her look with a pair of hoop earrings by designer Isharya and is also rocking a pair of beige peep-toe strappy heels – the perfect finishing touch to an elegant look. Selena is positively glowing here – and she should be – after all, she has Bieber Fever, and symptoms include being the envy of every tween around.
