the chick (sort of obviously, i doubt i respectable dancer would shed clothes on a show like that), plus it's not all that surprising once you get a bit of background on her from the article, reached popularity through Big Brother, has gotten naked on that show before (again, not really surprising)
I didn't see nipples, so I wouldn't say completely naked. But damn, she has a nice ass.
Did you watch the whole video? I felt the same way you did watching it in the beginning. It was a little to far in the beginning, but at the very end she takes off her g-string and you can see her bush.
I was like WTF prepare for a new show, Dancing with the Pornstars.
