Brooke Mueller was arrested while vacationing in Aspen, Colorado for felony cocaine possession with the intention to distribute early Saturday morning.

In a statement released by the Aspen Police Department, Charlie Sheen's ex, 34, was also busted for a misdemeanor 3rd degree assault charge.

The mom of 2-year-old twin sons Bob and Max was released from Pitkin County Jail Saturday morning when she posted the $11,000 bond. Mueller has a District Court date of December 19.

On Christmas day in 2009, Sheen, 46, allegedly held a knife to Mueller's throat and threatened to kill her. He later pled guilty on lesser charges and spent time in rehab, not jail. Since the incident, the two had lived apart, although their divorce wasn't officially granted until this past May. A source told Us Weekly in August that the parents have been "getting counseling and therapy [with] the boys" and Mueller, who has struggled with substance addiction, is "actually responding to treatment."
