WATCH - Katy Perry Celebrates Her 29th Birthday

Katy Perry made teenage dreams come true when she rocked the auditorium at Lakewood High School in Colorado. The pop star sang "Roar" and "Fireworks" as an honor to students who won a lip singing competition put on by Good Morning America. Undoubtedly, Perry's performance was the highlight of the students' school week (I know it would have been mine), but it was also a special day for Perry who celebrates her 29th birthday today.
