Charlie Sheen hasn't been in the tabloids much lately, but it seems his most recent ex-wife Brooke Mueller is picking up the slack.

Mueller, 34, was arrested in Aspen, Colorado on Friday night after another woman reported the erstwhile Mrs. Sheen assaulted her at a nightclub.

When police caught up with Mueller at another club and arrested her for the attack, they discovered she had enough cocaine on her person to also levy a charge of possession with intent to distribute -- a class four felony.

She posted bond of $11,000 and is due back in court on December 19.

Mueller is no stranger to drug problems. She's done multiple stints in rehab, and during her divorce from Sheen, both sides claimed the other was an unfit parent due to substance abuse.
