Like the good book says, "It's better to give than to receive." Katy Perry took this to heart when she gave Lakewood High School the gift of a lifetime on her 29th birthday.
The Colorado school was treated to a special concert by the pop superstar, which Good Morning America broadcasted live on Friday. The 2,700 students and staff of Lakewood High were awarded the honor over four other finalists in a Roar lip-dub contest.
"I'm 29 and I feel great," Perry told GMA's Sam Champion. "I still feel like I'm 13 sometimes. Obviously you can tell by my music and my spirit ... I just loved all the participation and the unification ... of all you guys coming together and roaring in one shot! That was so cool!"
