DETROIT (Reuters) - Rapper Eminem and his ex-wife are ready to remarry after picking up a marriage license on Thursday -- the latest twist in a turbulent relationship made famous by a hit song in which he fantasized about killing her. Eminem, whose real name is Marshall Mathers III, and Kimberly Mathers applied for a marriage license in Macomb County, just north of Detroit on Monday, an official in the clerk's office said on Thursday.The marriage license, which cost $20, is valid for 30 days. A representative for the couple came on Thursday afternoon to claim the license, the official at the clerk's office said.

Eminem, 33, whose 2000 hit "Kim" is a graphic rap fantasy about his former wife's death, told a Detroit radio station last month the couple had reconciled and would probably remarry.Published reports have said the two plan to marry on Saturday in the gritty Detroit suburb of Warren where they both once lived, just beyond the border of Detroit, 8 Mile Road, used as the title for Eminem's semi-autobiographical 2002 movie.The Mathers married in 1999 and their divorce, which prompted a custody battle over their young daughter, was finalized in 2001.Last year, the hip-hop superstar was treated for addiction to a sleep medication and had to cancel his European tour. His greatest hits collection, "Curtain Call," was released in December.Eminem has denied he plans to retire but suggested he could take a break from recording and performing."I'm at a point in my life right now where I feel like I don't know where my career is going right now," he told Detroit radio station WKQI-FM last month in the only interview he granted to promote the album.
