Mr. West is in the building. Well, he may be during Sunday's big night for all things NBA. According to a Deadspin tipster, Rihanna—who's been previously reported to perform at the 2011 NBA All-Star Game halftime show this Sunday—will be joined for a "surprise" special guest appearance from Kanye West where the two will duet "All of the Lights." Yes, the only time we pray that Yeezy crashes the stage.
