Katy Perry performs at Lakewood High School
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."
