Eminem's Ex-Wife Sent To Jail

Eminem's ex-wife is back in jail, after she dropped

out of a court-ordered drug treatment program, official allege.

Kim Mathers was released from jail on March 1

and ordered to attend the drug program after she was convicted of using cocaine,

while on probation.

She was ordered to serve 30 days in county jail

and was then transferred to a drug treatment program for 90 days.

"For whatever reason, she left the program

she was attending so the judge ordered her back to jail," Capt. John Roberts,

the jail commander, told The Detroit News. "For right now, it's ordered

by the judge that she complete her sentence in jail."

In January, Mathers pleaded guilty to possessing

25 grams or less of cocaine and failing to give space to an emergency vehicle

after a traffic stop.

Mathers' jail stint will end May 12.
