News anchors for "Good Morning America" announced on Aug. 13 the twelve dance couples set to compete on the all-stars season of "Dancing With The Stars."

George Stephanopoulos and Lara Sepncer revealed the pairs on a big screen outside of the news studio in New York's Times Square before a live crowd. 

Season 15 of ABC's hit show is unlike previous seasons - for the first time ever, the lineup features exclusively celebrities who have competed on the show before. The contestants are a combination of previous winners, finalists and most popular stars.

Additionally, the "DWTS" champions will have new partners this time around. Shawn Johnson, who won season 8 with partner and professional dancer Mark Balls, will team up with Derek Hough. Ballas will dance this time around with "Life's A Tripp" reality star Bristol Palin. 

The list of celebrities and their dance partners who will return to the ballroom to compete for the mirrored ball trophy are:

Emmitt Smith and Cheryl Burke  

Shawn Johnson and Derek Hough

Kirstie Alley and Maksim Chmerkovskiy 

Melissa Rycroft and Tony Dovolani 

Pamela Anderson and Tristan McManus 

Kelly Monaco and Valentin Chmerkovskiy

Joey Fatone and Kym Johnson 

Helio Castroneves and Chelsie Hightower 

Drew Lachey and Anna Trebunskaya 

Gilles Marini and Peta Murgatroyd

Viewers still have a chance to vote for the 13th contestant. Voting is available online at ABC's official "Dancing With The Stars" website until August 24. Carson Kressley, Sabrina Bryan and Kyle Massey are the three celebrities to choose from to fill the 13th slot. The celebrity who wins most votes will be announced, along with who will be his or her partner, live on Good Morning America on Aug. 27.   

The two-hour season premiere of "Dancing With the Stars" all-stars season is on Monday, Sept. 24 at 8 p.m. Eastern Time on ABC.
