Tonya Harding and Jeff Gillooly

The former U.S. figure skating champion is best known for conspiring with her then-husband, Jeff Gillooly, to attack competitor Nancy Kerrigan, but the pair also made headlines with the release of their "Wedding Video" sex tape. The video -- the gown she wears is actually a Halloween costume -- was made in the early '90s, but Gillooly sold the video, and stills from it were published by Penthouse magazine in 1994.
