Put your hands together, Hollywood! The national tour of ‘80s metal musical Rock of Ages followed up its starry opening at L.A.’s Pantages Theatre with a trip to TV land on Lopez Tonight. Tony nominee and American Idol heartthrob Constantine Maroulis took center stage with soon-to-be Broadway leading lady Rebecca Faulkenberry, and the pair brought the house down wailing on rock anthems "Here I Go Again" and "Don’t Stop Believin'." To see them in a smoky room, check out the video below!
