Years before Brooke Mueller's Christmas 2009 incident with husband Charlie Sheen -- he faces up to eight years in prison for alleged assault -- the future celebrity wife was building a rap sheet of her own.

Mueller, now 32, was arrested twice in the state of Florida, RadarOnline reports. In September 1996, she was cuffed for DUI and damage to property.

She got into deeper trouble in March 2001, when she was arrested for cocaine possession -- a third-degree felony. The charges were dropped after tests revealed she had no drugs in her system.

In the aftermath of her Dec. 25 fight with Sheen (a sworn affidavit reveals that he threatened her with a knife), Mueller was spotted having a low-key celebration with friends at Aspen celeb hangout Caribou Club on Monday. Her twins with Sheen, Bob and Max (born earlier this year) were photographed in the care of a nanny earlier that day.

Meanwhile, Arnold Mordkin, the Pitkin County, Colorado District Attorney who may prosecute Sheen, tells the case is "going on the backburner" until a February court date.

Mordkin tells Us that he has until Feb. 8 to decide whether or not to decide to file charges against Sheen. In the meantime, he plans to "carefully review" police reports, and may ask for additional investigative work before making his decision. As for reports that Mueller may not be cooperating with police, the District Attorney says the case could go forward with or without her. "In a domestic violence case, one does need to have the complaining witness to help out, so to speak," he explains, "but that can be acquired by a subpoena and testimony required."
