These pairs have been reported so far: Tom DeLay and Cheryl Burke, Donny Osmond and Kym Johnson, Aaron Carter and Karina Smirnoff, Mya and Dmitry Chaplin, Debi Mazar and Maksim Chmerkovskiy, Chuck Liddell and Anna Trebunskaya.

On Wednesday, Chmerkovskiy said he was "working on" Mazar's dancing skills. The Entourage actress admitted rehearsals have been "tough," and thanked him on Twitter for being "super patient."

"I feel the music, but I was never taught the footwork. work!!" she wrote. The show premieres Sept. 21.
