Last week, Rihanna was announced as the halftime performer for the 60th NBA All-Star Game, but according to sports blog Deadspin, Kanye West is also scheduled to give a "surprise" performance during the show.

An unnamed tipster let it spill that Kanye will join Rihanna on stage to deliver his single 'All of the Lights.' The track, which appears on his latest album, 'My Beautiful Dark Twisted Fantasy,' features vocals from 11 singers, including Elton John, Alicia Keys, Fergie and John Legend. In addition to sharing the stage with Kanye, Rihanna will also perform the singles 'Only Girl (In The World)' and 'What's My Name?' from her recent album 'Loud.'

Lenny Kravitz will be on hand to perform his new single 'Come On Get It' during player introductions, while Melanie Fiona will sing Canada's National Anthem before the game. Keri Hilson, Cee Lo Green and Cali Swag District are also among the scheduled performers at the 2011 NBA All-Star Weekend festivities.

The NBA All-Star Game tips off on Sunday (Feb. 20) in Los Angeles at 5PM PST.
