The 'Celebrity Big Brother' winner has opened up in a new Channel 5 documentary called 'Katie Price: In Therapy' and even said she would like Jane Pountney - who had an affair with her husband last year - to "die in a car crash' or "get an illness she'd suffer and die from".

She told mental health practitioner Dr Claudia Benant on her forthcoming TV series: "My head is full of stress, upset and pain. I'm sad, hurt. What it's like -- when I caught them? It's like two people have been murdered for me.

"I know this is harsh but if Jane could die in a car crash or get an illness to make her suffer and she'd die from it, I'd be a very happy woman."

However, the doctor thinks Katie's anger towards Kieran - who she has two children, son Jett Riviera Hayler and daughter Bunny Hayler with - has something to do with her "early years" and the breakup of her parent's marriage, when her mother Amy left her father, Ray who had cheated.

Claudia said: "Two dads and one mum is a triangle. It still exists for you."

The former glamour model responded with a remark about her ex-husband 'Mysterious Girl' hitmaker Peter Andre, that when they were together it was a love triangle between them and his management.

Katie replied: "That's funny you say that because my first husband Pete (singer Peter Andre) -- it was always the management, Pete and me."

'Katie Price: In Therapy' airs on Channel 5 on August 25.
