The 31-year-old reality star said it was 'not an easy decision' after filing for divorce from NBA star Kris, 26, after just 72 days of marriage on the grounds of 'irreconcilable differences'.
In a statement to E! - which screens her TV show - Kim said: 'After careful consideration, I have decided to end my marriage. I hope everyone understands this was not an easy decision.
'I had hoped this marriage was forever, but sometimes things don't work out as planned. We remain friends and wish each other the best.'
Kris, meanwhile, says he is devastated by Kim's decision, with TMZ claiming he only learnt she was divorcing him this morning.
'I'm committed to this marriage and everything this covenant represents,' he said in a statement via his representative.
