Katie Price's cheating best friend has been dumped by her husband.

The former glamour model was left heartbroken when she discovered Kieran Hayler had been sleeping with Jane Pountney, and the affair has had its toll on her pal's marriage too.

Speaking to The Sun newspaper, an insider said: ''He would have been able to forgive a few slip-ups but this ended up being so much more.

''He is shocked that the woman he loved would hurt so many people, including him.''

Meanwhile, it is said Katie sees the end of her former friend's relationship as karma after the breakdown of her own marriage as a result of the affair.

A source added: ''Katie's view is that Jane will end up with nobody - sad and alone.

''She feels terrible for Derrick but wants Jane to suffer some of the emotional pain that she has gone through. In her view, this is the ultimate case of Karma.''

The star sees the whole incident as a serious ''betrayal'' by two people she trusted - and she took to Twitter yesterday (23.05.14) and hinted at the pain she's going through.

She tweeted: ''This has been the case - 'The saddest thing about betrayal is it never comes from your enemies.'''
