Eminem’s ex-wife Kim Mathers blames the end of their marriage on the rapper’s constant cheating during their relationship. The singer, real name Marshall Mathers, and Kim have had a turbulent on-and-off relationship for nearly 20 years, which resulted on 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.”

Kim says she found out about his affairs, “Just from word of mouth (and) walking in on him a few times.” The 32-year-old confirms she caught him cheating saying, “Yeah, on his (tour) bus.”
