PHOTOS: Miley Cyrus's X-Rated Performance At The MTV VMAs + Hilarious Celebs Reaction

 Miley Cyrus fans may have thought her performance at the MTV VMAs was a bit too much when the 20-year-old singer was joined by singer Robin Thicke on stage for a rendition of his hit single Blurred Lines and she wasted no time stripping down to a tiny gold bikini.

Miley then proceeded to shake her pert derrière in the 36-year-old star’s face and draped herself all over him during the family friendly show.

Horror was written on the faces of fans as Miley stuck her tongue out while she writhed and gyrated around the married father-of-one.
