Allen reveals third nipple on TV

Lily Allen has revealed she has a third nipple - and shown it to Friday Night Project viewers.

The singer was talked into displaying the oddity, on the side of her breast, by contestants and audience members at the Channel 4 show.

It first registered with her when she heard Chandler Bing from Friends speak about his "nubbin".

"I thought, 'I've got one of those,'" she explained. "So I went to the doctor and he said, 'It's a third nipple'. Apparently, one in 10 people have them."

Allen pulled down her top and called on a camera man to zoom in on the dimple.

The clip has become one of the most watched on YouTube with more than 400,000 views.
