According to a Deadspin tipster, Rihanna, a previously announced performer at this Sunday’s NBA all-star game, will be joined by surprise guest star Kanye West. The two will do “All of the Lights†together. Amazing! (And you know you can trust Deadspin on these rumors — they were right about Brett Favre’s penis.) By the way, Elton John is also credited on that song: Can he make an appearance on Sunday, too? [Deadspin via Consequence of Sound]
