Former cab driver Mark Croft has again denied being unfaithful to pregnant Kerry Katona following claims he cheated on her with yet another woman.

Samantha Riaz, 29, claims she had a brief affair with Croft last July after meeting him in a club, with the two sharing a rendezvous weeks later at a hotel near the Katona's home in Wilmslow, Cheshire.

Miss Riaz says he initially tried to hide his identity, introducing himself a wealthy surveyor, and later sent a series of lurid text messages.

Denial: Mark Croft, with pregnant wife Kerry Katona last month, has hit back at new claims he's been unfaithful

She told The Sun: "I didn't know he was married."

The Chiswick-based 29-year-old claims Croft made contact with her again last week to arrange a reunion, where he allegedly told her: "[Kerry's] alright, but, she's not my cup of tea. It's about the money, innit? Forget her."

In a recording of what Miss Riaz claims is a conversation between her and Croft, she asks: "What was last summer? You cheated on her. Did it mean nothing, you and I?"

The male voice responds: "No, course it did! I wouldn't be ringing you now if it didn't. Me and Kerry have fun but it's more than that with me and you innit?"

Kerry's spokesperson Max Clifford responded to the allegations today, telling the Mail Online: "It's absolute nonsense."

"He's never even met this woman. The text messages are not from him and the voice in the phone call sounds nothing like him."

Last year, the couple, who are currently starring in their own MTV reality show Crazy In Love, endured reports Croft had slept with a barmaid while Kerry was pregnant with their daughter Heidi.

But there is yet more controversy surround the pair - reports emerged over the weekend alleging Kerry, who is four months pregnant with her fourth child, snorted cocaine at a party on New Year's Eve.

Mr Clifford denied the tabloid report, saying: "It's all nonsense - she had a drugs test in January."
