The ex-wife of rapper Eminem (search) on Wednesday was to begin treatment for drug abuse at a facility in Minnesota, a spokesman for the Michigan corrections department said.

Earlier this week, Macomb County Circuit Judge Edward Servitto released Kim Mathers (search) from jail early so she could go to the Hazelden drug treatment center in Center City, Minn., corrections spokesman Russ Marlan said.

Mathers had been sentenced to 120 days in jail and was not scheduled to leave until December, Marlan said.

She is scheduled to be in drug treatment for 30 days. If she successfully completes it, Marlan said Mathers will continue her two-year probation, which is set to end in January 2006.

It's not the first time Mathers has tried treatment. She twice has dropped out of a court-ordered drug treatment program and served some jail time earlier this year after dropping out.

She was placed on probation after pleading guilty to charges of possessing 25 grams or less of cocaine and failing to give adequate space to an emergency vehicle. The charges stemmed from a 2003 traffic stop in St. Clair Shores.

Mathers and Eminem, whose legal name is Marshall Bruce Mathers III, have a daughter, Hailie Jade Mathers.
