Katie Price has banished Kieran Hayler to a log cabin at the bottom of her garden.

The glamour model is punishing her husband by making him sleep in the shed at the edge of her £2.5 million home after discovering he was having a ''full blown sexual affair'' with her married best friend, Jane Pountney.

Kieran - who is the father of her nine-month-old son Jett as well as the pregnant star's unborn baby - has been subjected to a worse fate than Katie's former exes since she moved both Alex Reid and Leandro Penna to plush guest bedrooms following the breakdown of their relationships.

An insider told the Daily Mirror newspaper: ''Katie had the cabin built for [her 12-year-old son] Harvey for when he grows up. But now she has suggested Kieran stays there while she figures everything out.

''In the end, she ended up throwing Leo and Alex out, but at the moment it looks like Kieran is getting the long stay car park treatment for now.

''She is feeling very vulnerable and is at a real loss. It is all so sad. By having Kieran in the log cabin, it gives her the space to sort her head out and keep tabs on what he is doing.''

Meanwhile, Katie - who is also a mother to Junior, seven, and six-year-old Princess Tiaamii - is determined to divorce the builder after discovering he might have had a second fling with none other than Prince Harry's on/off girlfriend Cressida Bonas' cousin.

The 35-year-old reality star confronted Kieran's ex April Bonas over the phone about rumours she had cheated with him just days before the couple's romantic beach wedding last year.

A friend told The Sun newspaper: ''Katie and April spoke on the phone and she asked outright if she had slept with Kieran while they were together.

''April admitted they'd had a fling in the past, but was adamant that nothing had happened during Kieran's relationship with Katie.

''Katie quizzed April about everything she knew about what Kieran was doing before their wedding.''

Kieran has reportedly reached out to Jane's husband Derrick Pountney - who has claimed the infidelity was just a ''storm in a teacup'' - for help persuading Katie to forgive him.
