‘So You Think You Can Dance,” the hit reality competition on Fox comes to a close this week. According to organizers, Mary J. Blige, Leona Lewis and Jennifer Lopez will be in the building to close out the season with performances.

Speaking of Jennifer Lopez’s upcoming performance, SYTYCD choreographers say: “We’re steering clear of some big jumps,” referring to the “Louboutins” singer’s fall at the 2009  American Music Awards. “I feel like we don’t have to be dangerous anymore … Though I appreciated seeing guys with their shirts off personally — [there will be] no sweaty backs, no shirtless guys. We’re going to have some classy looking guys.” (PEOPLE)

The ‘So You Think You Can Dance’ season finale airs Wednesday at 8pm (on Fox).
