It has been eight years since Britney Spears and Madonna shocked the world with their steamy onstage kiss on the lips at the MTV awards.
And last night it was a familiar scene as the 29-year-old received a smooch from Rihanna as they performed onstage at the Billboard Music Awards in Las Vegas.
The 23-year old Barbados born singer planted the wet one on Spears's cheek after they performed her hit single S&M.

Both women were suitably clad in bondage-style body suits as they took to the stage.
While Spears slipped into a black suit, Rihanna opted for white.

Spears's vigorous work-outs for her up-and-coming Femme Fatale tour proved to be paying off, with the blonde looking incredibly toned in her stage costume.
While Spears lip-synched her parts in the song, her stage antics were nothing less than crowd pleasing and the pair certainly didn't disappoint with their very steamy performance.Spears also donned a bondage-style mask complete with bunny ears as she wrapped her wrists up in chains.

As always Rihanna turned up the heat on stage as she writhed around on the stage floor, while a pair of male hands attempted to grab her from underneath.
The Umbrella singer was also adorned with the kinky metal chains.

The two women topped off their show with a sexy pillow fight, hitting the male dancers with the bedding until feathers flew in the air.
The kinky performance was certain to make one man happy.
