Ex glamour model Katie, who is six months pregnant with Kieran's second child, has accused Kieran on Twitter of having a "full blown sexual affair" with her best friend Jane Pountney for seven months, however the Jane's husband Derrick has denied this.
Speaking to reporters outside his home yesterday afternoon, Derrick said: "A lot of this drama has been a storm in a teacup and there's a lot of misunderstandings to sort out.
"Now Katie has gone and put the whole thing for everyone to read about on Twitter, which she didn't really need to do, and a drunk kiss has turned into a full-on affair."
Mum-of-four Katie, 35, stunned fans yesterday after announcing on Twitter that she is to divorce Kieran, just 16 months after they married in the Bahamas.
She then continued by branding Kieran "a disgusting human being" and describing Jane as a "wh*re home-wrecker sl*t".
Neither Kieran, 27, or 49-year-old Jane have commented on Katie's claims.
Hours after posting the messages online, Katie was pictured visiting Jane and Derrick's home amid reports that she was about to have a "showdown" with her.
Dressed in tiny turquoise shorts and a pink jumper that covered her little baby bump, Katie looked furious as she stalked up the driveway before heading inside.
Kieran was then spotted turning up, along with Derrick and the foursome spent an hour or so discussing the situation with the curtains drawn.
Builder and part-time stripper Kieran is then said to have left by himself, before Katie headed outside and kissed Derrick on the cheek, before heading home.
Following this confrontation, Katie released an official statement, in which she said her "heart is breaking".
Writing on her official website, she said: "I appreciate most people will have seen my tweets on the subject of my marriage to Kieran.
"I make no apologies for them though it will be appreciated that, sending them immediately after Kieran confirmed to me what he had been doing for the last 7 months, those tweets were a sign of my heart breaking."
Katie added: "That he was doing it with a close friend of nearly 20 years is hard to understand."
Celebrities have since offered their support to Katie, including her good friend Rylan Clark.
This has come just days after Katie announced that she is unexpectedly six months pregnant with Kieran's second baby.
Katie already has a son called Jett with Kieran, who was born eight months ago, 11-year-old Harvey - who she had with footballer Dwight Yorke and Junior, eight, and Princess, six, from her marriage to Peter Andre.
She had no children with her second husband, cage fighter Alex Reid.
