The 38-year-old television personality has admitted she ended up sleeping with a man in the midst of his divorce after being introduced through her workout buddy Mark Smith.

She shared: "During our final workout, Mark tweeted a picture of us. One of his high-profile friends texted him, saying he had seen the snap and was dying to meet me ... 'Was he single?' I asked. 'Yes,' said Mark. 'Perfect! Give him my number.' Well, there's no harm in texting ...

"The sparks didn't fly. I couldn't put my finger on it. There was something clinical about it. Maybe he's a dark horse, I decided. Sadly, I was soon to discover that he wasn't hiding anything. That same emotional detachment continued when we eventually ended up falling into bed together."

And Katie - who has five children and is married to her third husband Kieran Hayler - admitted she was left "squirming" when she found out he was married.

She confessed: "He had a wife he claimed to be divorcing but they had three kids together. Inside I was squirming. 'Oh, f***ing hell, Kate, what have you got yourself into?' I thought. I could've kicked myself [...] Mr. X was in the throes of a divorce, but there was a large part of me that was convinced he would have played away even if he'd been in the perfect relationship."

However, the star insisted that she has learnt from her mistakes and is thankful she managed to get out of the relationship before she made any "deep emotional ties".

In an extract from her new autobiography Reborn published in The Sun newspaper, she added: "Not long after, his ex-wife got in touch with me and asked if we'd been seeing each other. I held my hands up.

"I felt horribly like 'the other woman' even though, like his wife, I'd been taken in by Mr. X. We actually ended up texting, like some first wives' club. But, unlike her, I thanked my lucky stars I could close the door on Mr X without any deep emotional or family ties."

The 'Loose Women' star refers to the man as 'Mr. X' in the book as to protect his identity as she says "there is a family involved."
