We love to catch celebrities unwittingly showing them. Sometimes it's an genuinely unintentional nipple slip, other times it's obvious they're doing it for attention. But we've never had a celebrity show off her nipples on national television. Especially not a third nipple. But that's exactly what British singer, and cutie, Lily Allen did.

Yes, Lily Allen has a third nipple, and she's definitely not afraid to show it off. She actually whipped it out in the middle of an appearance on a British game show, and had the cameras zoom right in. Now you know you're never going to see that on American TV.
