ABC announced the full cast of "Dancing with the Stars All-Stars" on Friday as the hit show enters season 15. The "All Stars" season will feature a lineup of six past winners and six runner-ups from past seasons set to air on September 24.

Season 15 of "Dancing With The Stars All-Stars" will see six winners who were some of the most popular cast members ever go head to head for the trophy. The others on the lineup include a few second runner-ups in addition to some who were eliminated too early getting a second shot.

The announcement was made two months before the "DWTS" season premieres at the Television Critics Association summer press tour Friday.

Kelly Monaco, the first ever winner and "General Hospital" star, will compete against past winners such as Drew Lachey, Emmitt Smith, Apolo Anton Ohno, Joey Fatone, Helio Castoneves and Shawn Johnson. Those who will be fighting for a second chance include Giles Marini, Melissa Rycroft, Pamela Anderson, Bristol Palin and Kirstie Alley.

The best part is that viewers, which have amounted to a record-breaking 22.5 million at one point during season 12, can vote for the final contestant wildcard. Voters can elect Sabrina Bryan of season 5, Kyle Massey of season 11 or Carson Kressley of season 13 for the final slot.

The cast has not been assigned their partners as they have been in past seasons for announcements. Partnering will be announced in August ahead of the season premiere.

Season 15 of "Dancing with the Stars All-Stars" will premiere on ABC on Sept. 24.
