Spears, Rihanna shock with onstage kiss at Billboard Awards

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.

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 on Sunday.

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, Digital Artist of the Year, Fan Favourite of the Year, Top Social Artist, Top Streaming Artist, Top Pop Album and Top Pop Album last night at the glitz ceremony.

Dominating the event alongside Bieber was rapper Eminem, who also picked up six awards - Top Artist, Top Male Artist, Top Billboard 200 Albums, Top Rap Artist, Top Rap Song and Top Rap Album.

Meanwhile, 'Bootylicious' hitmaker Beyonce Knowles was named the Artist of the Millennium at the Billboard Awards here and she received the trophy from none other than her mother.

The 29-year-old who began her career as a teenager with the group 'Destiny's Child', went on to win 16 Grammy awards and sold millions of albums over the years. Before accepting the award from Tina Knowles, with whom she runs the fashion label 'House Of Dereon', the singer put on an energetic performance of her latest single 'Run The World'.

Dressed in a silver mesh creation, which showed off all her curves, Knowles had the crowd up and dancing with her vigorous routine.

The star had her family and friends, including husband Jay-Z, cheering her on as she performed the single from her fourth solo album, titled '4'. She is also set to film her role as Esther Hoffman in a remake of 'A Star Is Born' later this year, with Clint Eastwood directing
