Rihanna turns up the sex factor in concert in Vegas
Rihanna's Diamonds World Tour hits its latest stop: the Mandalay Bay Events Center in Las Vegas. As you can see, the star sizzled on stage with her high-waisted shorts and bustier get-up. But Rihanna isn't just about the style - she's got a voice on her and the fans who were there saw a singer totally in command. Whatever's going on in her private life, she always delivers on the stage. See these photos of the sexy, sassy, Bajan-born award-winner.
