Mike 'The Situation' Sorrentino

A dancing star is nothing without a pro. ABC has unveiled the 12 pairings for Season 11 of Dancing with the Stars.

Two-time winner and defending champ Derek Hough will vie for a record third Mirrorball trophy with Dirty Dancing's Jennifer Grey. Two-time champs Cheryl Burke and Mark Ballas will also be in the running with Rick Fox and Bristol Palin, respectively.

Making a return to the parquet are Season 9 champ Kym Johnson, Season 3 runner-up Karina Smirnoff, Season 7 third-place finisher Lacey Schwimmer and Ballas' father, Corky Ballas, who was last paired with Cloris Leachman in Season 7.

Notably absent is Edyta Sliwinska, the leggy Polish dancer who's the only pro to have competed on all 10 seasons (her best finish was second place in Season 6 with Jason Taylor). Sliwinska, who's married to Season 1 champ Alec Mazo, announced on Twitter that she decided to return to school to study media communications at UCLA.

"I'm grateful to the show but my life can't be limited to DWTS," she wrote. "I hope you understand. Please know that you guys, the audience was the best part of the experience. Thank you everyone for such a nice response."
