Miley Cyrus Radio

Miley Cyrus and Rihanna have no problem stripping down on stage and in music videos, but they’re also very free with their bodies on the red carpet, too.

The pop princesses looked like they were attending the VMAs on Wednesday night when they rocked up to the the amfAR Inspiration Gala in Los Angeles in busty designer gowns.

Miley tried to out-boob Rihanna in a black, bondage-inspired dress, while Riri’s gorgeous gown featured a sheer bustier with purple flower petals glued on top to cover the nipples.

Both frocks were designed by Tom Ford.

Let us know which look you preferred: Miley’s or Rihanna’s!
