Katy Perry: Pop star performs at Lakewood High School

LAKEWOOD, Colo. — Pop star Katy Perry has performed a special concert for students at Lakewood High School.

Perry brought her show to the school Friday because students won a contest with a video they created. Their video, set to the tune of Perry’s hit single “Roar,” features more than 2,000 Lakewood students, some of them lip-syncing to the song.

The concert was broadcast live on “Good Morning America.”
