And The Winner For BEST DRESSED At Last Night's BILLBOARD Awards . . . Is CIARA . . . And It Wasn't EVEN CLOSE!!!


R&B singer Ciara literally MURDERED her competition at last night's Billboard Awards show. She wore a chainmail dress.

The dress was extremely risque. The singer, 30, who hosted the show, put her faith in some cleavage tape as she showed off her side boob in a very sexy silver chainmail dress at the T-Mobile Arena in Las Vegas.

The number exposed a great deal of her breasts, but she didn't look at all concerned as she posed like a superstar ahead of the event.

Ciara hosted last night's awards, and she did it for real. Ciara made SEVEN outfit changes during the production. We're still freaking over the wine-colored tuxedo gown in velvet.
