LATEST: Eminem'S ex-wife Kim Mathers cheated on the rapper while they were together - but only to get back at him. The rapper, real name MARSHALL MATHERS III, and Kim have had a turbulent on-and-off relationship for nearly 20 years, which resulted in them being twice married and divorced. She says the biggest challenges in the relationship were "him being on the road and on tour. That was like the big one and constant infidelities - all the time." However, Kim admits she started having her own affairs because she wanted to get back at Eminem saying, "I just really wanted love and attention from somebody. I was lonely and I didn't have very good self-esteem." Kim, who shares custody of the couple's daughter HAILIE, 11, with the rapper, claims there is no hope for a reconciliation saying, "I'm done."
