Are you ready for "Dancing With the Stars: All-Stars" (two-night premiere begins Mon., Sept. 24, 8 p.m. ET on ABC)? The cast sure is.

I caught up with returning champions Drew Lachey, Kelly Monaco and Helio Castroneves, as well as Pamela Anderson, Gilles Marini, Bristol Palin and Melissa Rycroft, the previous season contestants with even more to prove. While they all agreed there's plenty of competition in this all-star crop (six previous winners! Olympic athletes!), they had wildly different answers when asked to size up their biggest competition.

Is it Season 8 winner Shawn Johnson? Or her fierce (and fiercely sexy) No. 2 Gilles Marini? Will Season 3 winner Emmitt Smith dominate the dance floor paired with his lucky charm partner Cheryl Burke again? Or will wildcard Sabrina Bryan be the one to beat?

Watch the interview with the stars, above, to see what they think, and to find out who's planning to coast on charm and who's already afraid of cast sabotage.

"Dancing With the Stars: All-Stars" two-night premieres kicks off Mon., Sept. 24 at 8 p.m. ET on ABC.
