When Kieran admitted to being unfaithful, he gave a confession which included the details of his dalliances - including the fact he romped with Jane in Katie’s stables.
Now, the former glamour model, who is currently expecting her fifth child, has apparently decided she no longer wants to live at the swish pad due to too many “painful memories”.
“This sale will be a big part of that.”
Katie first moved into the West sussex mansion in 2010, with her then-husband Alex Reid.
Following her split from Alex, Katie got engaged to Argentinian model Leandro Penna and he soon moved into the house.
Kieran admitted to being unfaithful back in May, when he confessed to having a sexual encounter with Jane in the stables on New Year’s Eve, during a party being thrown by Katie.
“It was around 1am and I was hammered from drinking Porn Star martinis. I headed up to the stables where a friend of mine was meant to be staying and Jane followed me,” he told The Sun on Sunday. “We had sex standing up.”
Following his admission, Katie took to Twitter to hit out at the pair and has since speculated over whether Kieran could have cheated with other women too.
