Katie Price's ex-best friend Jane Pountney was also being cheated by her husband Derrick while she was sleeping with Katie's husband Kieran Hayler.
The ex-glamour girl was left devastated after she discovered her husband Kieran had been having an affair with Jane and now it has been revealed her partner Derrick was also having sex with 49-year-old receptionist and former WAG, Caron Armstrong, behind her back.
Caron, divorced from ex-Spurs footballer Gerry Armstrong, told The Sun on Sunday newspaper: ''Derrick and Jane haven't been intimate for a long time, which is why Jane went after Kieran. She'd have been flattered by his attention and in need of some affection.''
Caron claims their affair went on for ten years after Derrick and Jane had their youngest daughter, now six, and the passion went from their marriage.
She explained: ''Derrick has a high sex drive and he's starved of it at home.
''We always have sex when he comes round - it's the first thing we do. Derrick and Jane haven't slept together for three years.
''I knew things couldn't be good between them in the bedroom because he's been seeing me on and off for ten years.
''He says the spark fizzled out years ago and now they live more like brother and sister than husband and wife.''
Kieran, 27, wrote a letter to Jane dismissing their affair as just a ''dirty, sleazy sh*g'', and insisted he wanted to win back Katie, 36, who is pregnant with his second child. The pair also have nine-month-old son Jett and Katie's children from past relationships, Harvey, 12, Junior, eight, and Princess, six.
Caron claims Derrick spoke to her about Kieran's comments and he was annoyed the affair didn't mean anything to him.
Mum-of-two Caron recalled: ''We were lying in bed and Derrick talked to me about the state of his marriage like he never had before.
''He said his marriage is over, there's no going back, and he's going to see his solicitor on Tuesday to file for divorce. He told me he's no longer sleeping in the marital bed and has moved into an annex at the side of their house. They're now living separate lives.''
Derrick, 51, reportedly told his wife of 16 years about his own affair when Katie turned up at their home in West Sussex this month demanding answer's about Jane and Kieran.
Meanwhile, the brunette beauty has now kicked Kieran out of their mansion and claims she is divorcing him just 15 months after they tied the knot.
