Guess who just RSVP’d for Charlie Sheen’s roast tonight?

Sheen’s ex-wife Brooke Mueller has been playing it coy about whether she’s attending Saturday’s big event, but she just confirmed with organizers that she’s coming to the show, EW can exclusively report. Fellow ex Denise Richards is still not on the bill. EW’s Inside TV blog will have joke-to-joke live coverage of the sure-to-be-unusual event starting in a couple hours so check back. Meanwhile, here’s a list of celebrities taking the stage at the roast, and here’s the attending celebrities in the audience.
