The Channel 4 interview clip in which pop star Lily Allen showed off her third nipple, has become one of the most watched video on You Tube.
The 90-second clip has been viewed over 400,000 times on the site in a single day making it the fourth most viewed video.
The Smile singer, who hosted the channel's Friday Night Project, wanted to prove a point when Friends character Chandler Bing spoke about 'nubbin'.
"I've got one of those..So I went to the doctor and he said, 'It's a third nipple'. Apparently, one in 10 people have them," the Mirror quoted Allen, as telling him on the show.
As the audience including Mylene Klass watched, she got the camera to zoom in as she flashed the third nipple.
