In an explosive interview with WKQI-FM's (95.5) "Mojo in the Morning" show today, Eminem's ex-wife Kim Mathers flipped the tables on Em and cleaned out her closet live on the air for all to hear."I can't stand him. He's an absolutely horrible person, and he gets worse every day," Mathers said. "I vomit in my mouth whenever I'm around him or I hear his name. There's nothing left in me for him. Nothing at all."She categorized sex with her twice ex-husband as "bad," and said "he's not very well endowed." She added, "If you're going to have sex with Marshall, make sure you have a little blue pill, because otherwise it does not work."Mathers said Em text-messaged her on Thursday when he heard she was going to appear on the "Mojo in the Morning" show and blasted her for going on the air.The two were first married in 1999 and divorced several years later. They remarried in January 2006 at Rochester's Meadow Brook Hall, and Em filed for divorce in April of last year.A call to Eminem's Interscope Records publicist was not immediately returned.
