Kieran Hayler has written a letter to Katie Price's former best friend dismissing their affair as just a "dirty, sleazy sh*g."
The builder and part-time stripper, who has admitted sleeping with married Jane Pountney, 49, is still desperate to win back his pregnant wife Katie, and insists he is seeking help at a rehab clinic for a compulsive addiction.
In a letter seen by The Sun newspaper, Kieran tells Jane: "I told you everything you wanted to hear so I could sleep with you.
"And that's all it was, a dirty, sleazy sh*g to feed an addiction that I am ashamed to say I have.
"But I am going to get help because I love Kate with all my heart and I do not want to lose her and I want us to be stronger than ever once this all passes."
He continues: "I was never ever going to leave Kate for you. I am so glad we got caught because now I can get help and I can start a new fresh life with Katie with good people in our life and positive future."
The 27-year-old claims he wrote the letter during £2,500-a-day rehab sessions, which he started last week, and he insists having therapy has helped him to realise he has a "compulsive addiction."
Hayler is still hopeful he can repair Price's broken heart and save their marriage, after tying the knot last year, for the sake of their nine-month-old son Jett, as well as Katie's children from past relationships, Harvey, 12, Junior, eight, and Princess, six.
But Katie, 36, has slammed her husband and Jane again on Twitter, after reading Kieran's tell-all interview, in which he revealed the pair had unprotected sex in Katie's stables and on a family holiday during their seven-month affair.
