London, Sep 2 - American singer Eminem's ex-wife Kim Mathers has destroyed the 'not very well endowed' rapper in a new radio interview saying he is 'a flop in bed'.

Eminem, real name Marshall Mathers split from his wife last year after another attempt at their tempestuous marriage. They've taken pops at each other in the past, but now its got nasty, reports thesun.co.uk.

'I can't stand him. He's an absolutely horrible person and he gets worse every day. 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 said in an interview to Detroit, Michigan station WKQI.

'He's not very well endowed. If you're going to have sex with Marshall, make sure you have a little blue pill, because otherwise it does not work,' she added.
