SPOILER: Nancy Grace And Chaz Bono To Dance With The Stars

If it's true what the say about the number 13, then the cast of the 13th season of ABC's Dancing with the Stars, leaked via Twitter by DWTSGossip in advance of its scheduled announcement on tonight's episode of Bachelor Pad, had better hold on to their lucky charms — or at least come up with some lucky dance moves.

The most surprising names on the list are Nancy Grace, Casey Anthony trial commentator and controversial host of The Nancy Grace Show; Chaz Bono, son of music and film icon Cher and a female-to-male transsexual, who will be partnered with a female dancer; Ryan O'Neal, 70, actor and father of Tatum O'Neal; and David Arquette, separated husband and Scream 4 co-star of Courtney Cox Arquette.
