Kristin Cavallari, Elisabetta Canalis and More Arrive at ‘Dancing With the Stars’ Rehearsals (PHOTOS)

The cast of ABC’s Dancing With the Stars season 13 won’t officially be announced until later tonight, but some of the A-listers rumored to be on the show were already spotted making their way to rehearsals on Sunday.

Among those snapped by photographers yesterday were reality TV star Kristin Cavallari; Italian actress – and George Clooney’s ex - Elisabetta Canalis; and what appears to be basketball player Ron Artest.

Will Kristin, Elisabetta and Ron actually appear on DWTS? We won’t know until the cast is announced during tonight’s episode of Bachelor Pad (8PM ET).

For now, though, check out photos of them as they arrive at rehearsals.
