The big show on Emmy night may actually take place after all the awards have been handed out – Grammy winner Mary J. Blige will perform at the 13th annual Entertainment Tonight Emmy party, at Vibiana in downtown Los Angeles after the telecast.

"I am so excited to break the news that I will be performing at the ET Emmy party!" Blige said.

The Sept. 20 party, sponsored by PEOPLE, will also feature music spin by DJ Samantha Ronson. Previous performers to headline at the party include Prince, Duran Duran, Billy Idol and Earth, Wind and Fire.
