Rihanna shows off her nipples in new video sneak preview

Rih-lly sexy .... singer poses in sheer white frock on video set

RIHANNA shows off her boobs in a stunning see-through dress in this sizzling sneak preview of her brand-new music video.

The 24-year-old's nipples poke through a sheer clingy frock that's slashed up to her thighs in snaps taken on the LA set of her Diamonds promo.
The track is the latest single from her seventh album Unapologetic - and the video looks like it will be packed with drama.

It's been an eventful weekend for Rihanna, who found time during the video shoot to sneak off and support ex Chris Brown at a launch party for his website in Beverly Hills on Saturday night.
The pair were inseparable all night and one partygoer even managed to capture a snapshot of them stealing a sneaky smooch.

Sneaky smooch ... Rihanna and Chris Brown steal a kiss on Saturday night

The couple split back in 2009 when Chris assaulted Rihanna at a pre-Grammy Awards party in LA.
He was convicted, given six months of community service and placed on probation for five years.
But the pair have been getting close again - and she dropped another hint on Twitter this weekend that they're officially an item.
She posted a passage from the Bible, titled "Forgiveness wins".
