Katie took to her Twitter page on Wednesday afternoon to reveal that she was divorcing Kieran, in a string of angry tweets where she accused the builder and part-time stripper Kieran of sleeping with her close friend Jane Pountney.
A friend of the former glamour model has now revealed that Katie had her suspicions that something was going on weeks earlier, but when she confronted Kieran about it, he denied anything was wrong.
Speaking to The Sun, the pal said: “Katie was concerned the spark seemed to have gone and had her suspicions something was going on. But when she confronted Kieran he always told her that she was mad or crazy.”
Meanwhile, Jane’s husband has revealed that he has known about his wife’s extra-marital activity with Kieran for “around four weeks”, but downplayed the idea of an affair, insisting it was more like “a drunken kiss”.
“That’s not the case. I knew about what had happened before today, it’s not new to me.”
The tricky situation is made even more complicated by the fact that Katie confirmed earlier this week that she was six months pregnant, just months after giving birth to the couple's first child together.
