Britney Spears & Rihanna Open the Billboard Music Awards

She always brings her A-Game, and Britney Spears teamed up with Rihanna for a fabulous opening performance on the 2011 Billboard Music Awards tonight (May 22).

The “Toxic” mommy and the “Russian Roulette” songstress not only had top-notch singing, but also provided quite the sexy stage show.

They joined forces on their remix of Ri-Ri’s super hot single “S&M” and the temperature in the MGM Grand Garden Arena in Las Vegas definitely raised a few degrees.

Prior to the gig, an eyewitness at the dress rehearsal told press, “Britney looked fabulous- better than ever. The opening is sexy and playful. Britney’s got a fantastic entrance. It’s epic.”
