Arquette will reportedly be 'Dancing'

The cast of the next edition of "Dancing With the Stars" won't be announced officially until Monday night during ABC's broadcast of "Bachelor Pad," but TMZ is reporting with certainty the identity of at least one participant.

The celebrity website posted a photo of "Scream" star David Arquette arriving at the "DWTS" rehearsal studio Thursday to meet with Kym Johnson, his future partner. She was the partner of Season 12 winner Hines Ward, so if the pairing is true, the estranged husband of Courteney Cox Arquette should be in good hands.

Other celebrities whose names have surfaced regarding their participation in Season 13 include Rob Kardashian, George Clooney's ex Elisabetta Canalis, Mike Tyson, NBA star Ron Artest and Christina Milian. Queen Latifah, Tiffani Thiessen and Nicole "Snooki" Polizzi all have denied reports that they'll be hitting the dance floor this fall.

The fan website PureDWTS speculated recently that Chaz Bono was in the running -- based on the fact that Cher's son started following "DWTS" pros Mark Ballas and Karina Smirnoff on Twitter.

The new season begins Sept. 19.
