WATCH! Rihanna and Britney's red hot Billboard performance

Wowza! The saucy pair sent temperatures soaring with a raunchy performance at the prestigious award ceremony

Wowza! It was a truly star-studded affair, but saucy starlets Britney Spears and Rihanna still managed to steal the show at the prestigious Billboard Music Awards in Las Vegas last night.

The cheeky pair sent temperatures soaring with an extra special performance of Rihanna’s risqué S&M hit, ending the raunchy show with a steamy smooch for the cameras.

The pop princesses opened the show at the glittering music event, teaming up to perform the recently released remix of Rihanna’s S&M song.

The Barbadian beauty began the track on stage alone, flanked by scantily clad backing dancers, with slinky chains around their wrists.

But halfway through her rendition, who should stop by? None other thanMiss Britney Spears.

The starlet surfaced from underneath the stage – to a flurry of excitement from fans – but seemed to be miming at some points during the performance.

Dressed in matching bondage-style bodices, fishnet tights and wielding sparking chains, the high profile duo each sung choruses and verses of Rihanna’s S&M song – the steamy lyrics of which caused a huge stir after its release earlier this year.

And if that wasn’t enough excitement for one night, the cheeky twosome even sealed the end of their sizzling performance with a steamy smooch – eight years after Britney's similarly attention-grabbing kiss with Madonna.

Other highlights during the star-studded night included chart topper Beyonce, who treated the audience to a scene stealing performance of new hit Run the World, the Black Eyed Peas, and US songstress Nicki Minaj.
