Brooke Mueller Off Limits at Charlie Sheen Roast Or Else?

Sources close to Mueller tell TMZ ... she wants her name "completely off-limits" when The Warlock is roasted in L.A. on September 10.

And Brooke may have the law on her side. In her divorce settlement, Charlie promises not to ever publicly discuss her drug use, and people in Brooke's camp are telling us, "He better not go there."

We're told Brooke's people are seriously considering sending Comedy Central a letter, demanding it not broadcast any anti-Mueller jabs.
