Jay-Z, Rihanna, Kanye

Rihanna will make her first major public performance since the Chris Brown assault six months ago by teaming up with not one, but two Jays.

The 21-year-old singer will join her mentor Jay-Z and Kanye West on the Sept. 14 debut of The Jay Leno Show to perform their new single "Run This Town," NBC announced. The song is off Jay-Z's upcoming album The Blueprint 3, in stores Sept. 11.

The trio is the first slate of stars booked on the not-exactly-a-talk-show show, which Leno has said will feature a looser and more interactive format with celebrity guests.

Brown pleaded guilty to felony assault on Rihanna in June and is expected to be sentenced Aug. 27 to five years' probation and six months of community labor.
