DETROIT (AP) -- Eminem's dysfunctional relationship with wife Kim has hit another low -- he filed divorce papers Wednesday, less than three months after remarrying her.

The filing on behalf of Marshall Bruce Mathers III, Eminem's real name, was confirmed by two employees of the Macomb County clerk's office. They didn't provide their names, citing an office policy.

The Grammy- and Oscar-winning rapper and Mathers remarried on Jan. 14, a month after the couple announced they were getting back together.

Their first marriage ended after two-plus years in October 2001 in an ugly legal fight that included a custody battle over their daughter, Hailie.

Though the marital issues of most rappers wouldn't make headlines, Eminem has used his tormented relationship with Kim, his high school sweetheart, as a source of his most popular and demented rhymes. He's killed her off in song and assailed her with his lyrics -- but that was before they got back together.

Eminem, 33, and Mathers, 30, reconciled in late 2004, and he announced in December 2005 that they would get back together.

The pair grew up in the suburbs along Eight Mile Road, Detroit's northern border.
