Britney Spears And Rihanna Perform At The 2011 Billboard Music Awards Rihanna & Britney Spears Rock The 2011 Billboard Music Awards PhotosBritney Spears and Rihanna are no strangers to media outbursts and saucy headlines so the latest news is nothing of a surprise.

The duo caused a flurry of feathers at the Billboard Music Awards as they danced and sung in matching bondage-style bodices, fish-nets and handcuffs to their joint hit “S&M”; before ending it with a pillow fight.

The singers sent temperatures soaring as they entertained the crowd with sexy masks, kicky chains and topless dancers whilst provocatively pole dancing. But the grand finale was a pillow fight and a smooch on stage!

The heat-racing performance sent feathers flying through the air and let audiences reminisce back to 2007 when Miss Spears kissed Madonna live on stage too.

The 2011 Billboard Music Awards were held at the MGM Grand Garden Arena in Las Vegas, Nevada and Britney surprised the crowd to perform her verse from their remix version of the song after RiRi, 23, took the platform.

Spears, 29, later rocked the show performing her hit song “Till the World Ends” alongside her Femme Fatale tour partner Nicki Minaj.

We feel sorry for the poor guy or gal who had to clean up the mess up after these sexy stars…
