The rumor mill was buzzing that Britney might be making her first awards show performance tonight at the Billboard Awards since her disastrous 2007 VMA’s appearance and it appears that it’s true! The word is Rihanna will be opening with a medley of California King Bed, Man Down and S&M with help from Brit Brit, and the show will close out with Brit and Nicki performing their “Till the World Ends (Remix)” with possibly some help from Ke$ha, who will also be in the building. The show airs tonight at 8pm on ABC. Can’t wait! @MarisaMendez
