Eight years after shocking the world by kissing Madonna onstage, Britney Spears repeated a tamer version of the act with Rihanna at the Billboard music awards on Sunday.
The 29-year-old pop princess received a hug and a wet one on the cheek from the R&B star as they performed onstage at the awards in Las Vegas.
The 23-year-old Barbados born singer kissed Britney after they performed her hit single S&M.
Both women were clad in identical bondage style body suit as they took to the stage. While Britney slipped into the black style of suit, Rihanna opted for white.
Keeping within the bondage theme, Rihanna crawled on her knees while Britney commanded and dominated her with a long chain.
Britney also donned a bondage-style mask complete with bunny ears as she wrapped her wrists up in chains.
Watching the show in the audience was teen pop star Justin Bieber, who scooped up six awards including the Best New Artist and Fan Favourite of the Year at the glitz ceremony.
