Johnny Depp performed a low-key gig in Hollywood last night to raise money for a children's charity.
The actor apparently strapped on a guitar and quietly slipped onto the stage at the Lucky Strike bowling alley, alongside Gene Simmons.
He also joined the house band for a version of 'School's Out' by Alice Cooper.
The concert was in aid of Mending Kids, a charity that provides free corrective surgery for children around the world.
