Bradley Cooper jokes about third nipple on TV

Hollywood hunk Bradley Cooper stunned American TV viewers this week by showing off his third nipple on camera, but the stunt was all part of an elaborate comedy ruse.

The Hangover star unbuttoned his shirt during a chat with Ellen DeGeneres to unveil the unusual feature, telling the host, "It's not good... I actually have a third nipple... Is that weird?"

DeGeneres asked the actor, "You have three nipples?... What is this, show and tell right now? What else do you have?"

Cooper then revealed his admission to be a joke by rolling up his shirt sleeve and adding, "I actually have a fourth nipple too," before showing off a "fifth nipple" on his leg.
