amfAR Inspiration Gala: Rihanna And Miley Led Hollywood's Leading Ladies' Boob-Off

The amfAR gala in LA this year was all about one thing: Boobs.

Hollywood's finest bared almost all in the competition to make the biggest splash at the event and we think the prize probably has to go to Rihanna and Miley Cyrus for their incredible boob-displaying outfits.

Rihanna went for a floor-length white Tom Ford gown with thigh split, and silver waistband. But really it was all about the risque boob-coverage. Or lack there of. We've also got to give a nod to those gorge pink metallic sandals.

All that covered the siger's modesty were a smattering of petal-shaped sequinnes and bead embellishments.

Miley also went for a Tom Ford outfit, contrasting with Rihanna in all black.

The former Disney star's dress was a demure full-length skirt but the top half was the polar opposite. Miley's modesty was covered with snake-skin textured black strips of material, covering her breasts and crossing at the neck.

An honorable mention should certainly go to Kelly Osbourne, whose simple black after party outfit showed off her enviable cleavage.

But even among those not being so brazen, making the most of thier female assets was clearly the order of the day.

Dita Von Teese, Natasha Beddingfield and Michelle Rodriquez all accented their cleavage in their amfAr outfits. We love the deep tones of Michelle and Dita's looks but have to admit Natasha's Canary yellow didn't quite do it for us.

Very little left to the imagination all round. Not that we're complaining of course. Yay for boobs!
