Britney Spears opened the show at the 2011 Billboard Music Awards, teaming up with ‘Love The Way You Lie’ singer Rihanna for a remix of her hit ‘S&M’. Britney then reappeared later in the show to debut her remix with Nicki Minaj for the hit ‘Till The World Ends’.
Britney and Nicki will be touring together as Minaj will be supporting Spears on her Femme Fatale tour in the summer. Minaj has revealed recently that she hope to do less collaborations in the future as she feels that she does far too many.
Rumours had been floating around that Britney Spears would be making a surprise special guest appearance at the 2011 Billboard Music Awards but nothing had been officially confirmed. The two singers will reunite for the Femme Fatale tour when it kicks off on June 17th.
