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."
Kieran is still hopeful he can repair Katie'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.
Katie posted: "@Kieran0322 and jane pountney the w**** were f****** all through France they have been f******* in my house the whole time even when I was home (sic).
"@Kieran0322 has confessed this today they are both lying cheating ****s (sic)."

Angelina Jolie says motherhood played a huge part in her taking on 'Maleficent'.
The actress - who has Maddox, 12, Pax, 10, Zahara, nine, Shiloh, seven, and twins Knox and Vivienne, five, with her fiance Brad Pitt - was happy to take on the role in the re-imagining of Walt Disney's 'Sleeping Beauty' as she was able to spend time with her children on set.
She told Collider.com "[Motherhood] had a lot to do with it. My kids are now all watching all of these movies and wanting to play with mummy. It was perfect timing to have them all on set, playing and being a part of the adventure with me. "
Jolie, 38, also credits the "bold" nature of the evil title character as a factor in her decision to take on the role.
She said: "For me, as an actress, I wanted to not do something where I'm taking myself so seriously, and trying to do something for myself and my art. I wanted to remember what it is to play and entertain, and try something bold.
"The artist in me felt that it's good to do something bold, every once in awhile, that you're not comfortable with and haven't done. I was a bit nervous to take her on. I don't have a big theater voice. I don't do things that are comedic. This is such a crazy idea. I'm a fairy. I'd come and hear, 'How was your day, honey?' And I'd be like, 'I was a fairy. I don't know.' But somehow, it's great to jump into things you're not sure of and you haven't done and that are a little scary. That's what we have to do, as artists."
The Oscar-winner - whose daughter Vivienne makes her acting debut as the young Princess Aurora - hopes that her children don't dedicate their lives to the big-screen and only wants them to take-up movie-making "for fun."
She said: "I just want them to like it and do it for fun, only. If, when they get older, they decide to be actors, I would just ask that that's not the centre of their lives. That can be an aspect, but I also want them to do many other things with their lives and get involved with many other things. I don't think it's a healthy focus, as a centre of your life."

Iggy Azalea learnt how to twerk from strippers in Atlanta.
The 23-year-old pop star perfected her butt-shaking dance moves at house parties before she found fame, and has revealed the performers in the strip clubs in the American city were an inspiration to her.
Iggy - who moved from Australia to the US on her own when she was just 16 - said: "I used to live in Atlanta, and that's just how everybody dances at house parties and stuff."
She added: "The best twerkers are probably all the strippers in Atlanta. They're pretty good."
The 23-year-old singer - real name Amethyst Kelly - has also revealed how she came up with her unusual stage name.
The 'Work' hitmaker says her moniker is a combination of her pet dog's name and the street in New South Wales, Australia, where her mother's house was located.
She is quoted by People as saying: "Iggy was my dog's name. My dad picked him up a week after I was born, and he named him after Iggy Pop. And Azalea is the street where my mother lived."

Christina Aguilera is sticking to a healthy diet during her second pregnancy.
'The Voice' USA coach reportedly gained 40 pounds while expecting her child Max - her six-year-old son with ex-husband Jordan Bratman - and is determined not to put on as much weight carrying this baby, her first baby with her fiancé Matthew Rutler.
A source told Life and Style Weekly magazine: "She is making much better choices and is adamant about staying healthy. She's telling everyone how vibrant and connected to her body she feels."
Christina had shed a lot of weight before getting pregnant and has so far been able to carry on with her healthy eating regime relatively easily.
Her man Matthew has also been doting on his pop star partner and getting her whatever she needs.
The insider added: "He's doting on her night and day and never leaves her side. He talks to the baby through her stomach - it's so cute."
One food Christina, 33, has developed an appetite for is blackened barbecued meats, a common craving among expectant ladies.
A source previously said: "The other day, she went nuts for a plate of blackened BBQ. She laughs about it, but she was also relieved when she found out this craving isn't all that strange."

Hilary Duff and Mike Comrie are trying to co-parent "peacefully."
The 26-year-old actress, who recently hinted she is trying to work things out with her husband after they announced their separation in January, insists they are putting their two-year-old son Luca's needs first.
Talking to Us Weekly magazine, she said: "We're really good friends and spend a lot of time together. We're just trying to figure out what makes us happy, but we have Luca as our priority. We're going to do it in the most peaceful way."
Meanwhile, Hilary says their two-year-old is keeping them on their toes.
She explained: "Luca's two, so he has a strong personality. He's spirited. That's a good word for him.
"He's talking a lot and trying to put words together, which is a big deal. But sometimes he does test me. I have a toddler bed on order, but he's already jumping out of his crib! I hear a thud and I'm like, OK, he tossed himself out. He's so funny. I say, 'What are you doing?' And he's trying not to smile because he knows it's kind of naughty.
"He opened his own door recently - I couldn't believe it."

George Clooney may wed at the country house where 'Downton Abbey' is filmed.
The 'Oceans Eleven' star whisked his fiancée Amal Alamuddin away for a romantic break in the English countryside this week, which took in Highclere Castle near London - where the period drama is filmed - and she was so taken by it, they made enquiries as to whether it could be used for their wedding.
A source told MailOnline.com: "George became close friends with Hugh Bonneville, who plays Lord Robert Crawley, when they did 'The Monuments Men' together last year.
"And they really hit it off. He contacted Hugh and asked him to arrange a private tour of the castle. Amal was blown away.
"When he saw his bride-to-be's reaction to the spectacular Victorian castle, set on 1,000 acres of parkland, he began making some discrete inquires about having their wedding performed there.
"And he was told they would be most happy to accommodate them."
Highclere is thought to be a good venue for the wedding as it is close to London and also to Heathrow airport, meaning George's family from America can easily fly, as can Amal's extended family who live in Dubai and Lebanon.
The castle is currently inhabited by the 8th Lord and Lady Carnarvon and their family and allows weddings, with prices to hire parts of the castle starting at $23,000 for a day.
The source added: "George loves the idea of marrying at the castle, because it's a glamorous place he could secure... Amal's Middle Eastern relatives would most certainly enjoy the exhibition, and the tour would make for a most memorable wedding."
Other venues the couple are said to be considering for the wedding are George's home in Lake Como, Italy, and Cabo San Lucas in Mexico, but it is thought Amal wants to be near where she grew up in the UK.
Another source said: "Amal grew up in London, and attended school in Buckinghamshire. "And she went to University at Oxford. She currently works in London so she has many close British friends."

Freida Pinto has an "obscene" number of shoes.
The 'Slumdog Millionaire' beauty admits to an obsession with footwear and has so many different pairs she can't count them all.
She told Harper's Bazaar Arabia: "They're my biggest obsession but I don't even know how many I have.
"It's a bit obscene for me, but I'm sure there are people that have way more.
"It's really weird though, because my love for shoes isn't because I want to wear them all. I mean, there are only so many days in the year, so it's impossible to wear all of them, but I have them because they're so beautiful, like works of art, and I love looking at them."
The Indian starlet and model was plucked from obscurity to win a lead role in Danny Boyle's 'Slumdog Millionaire', which went on to win eight Oscars, although she says she doesn't always feel pretty.
She said: "I was at an event with [model] Karlie Kloss last year and it was horrible standing next to her. She's a beautiful lady and I felt like a little ant."
Freida also says she felt like a star for the first time when she was dressed for the the premiere of her most famous film by Chanel.
She added: "It was amazing that the brand believed in me, and I felt very, very lucky. If you wear Chanel to a premiere, you feel like you've kinda made it."
Alongside Freida, another notable collector of shoes is Imelda Marcos, the former Philippine fist lady, who at one point had a collection numbering 3,000 pairs.

Miranda Lambert bought Carrie Underwood a motorbike.
The country singers recently collaborated on a duet of 'Something Bad' on the Billboard Music Awards, and as a thank you Miranda bought the 'Two Black Cadillacs' a new bike.
Next to her on a picture of her new hefty black two-wheeler, Carrie wrote on Twitter: "Well, it's not every day @mirandalambert buys you a motorcycle! Next stop, motorcycle driving lessons!!! #RansTheBest (sic)"
The singer also sent a message for Memorial Day in the US today, which celebrates those who have given their lives in the armed forces.
She added: "A GIANT thank you to our Armed Forces this weekend and every day for your sacrifices. #MemorialDayWeekend."
Carrie will have plenty of space to ride her new bike, as she and husband Mike Fisher bought 400 acres of land near to Nashville, Tennessee, in 2011, on which they have built their dream home.
The blonde beauty - who was catapulted to the spotlight after winning 'American Idol' in 2005 - has also been working on her fifth album, and has been writing her own tracks for it.
She recently said: "I've been writing quite a bit, it's exciting! It definitely has a different sound. There are some thematic things that are quite different. I love strong women. So I want things that I can get on stage and just feel empowered."

LeAnn Rimes say she and Eddie Cibrian "give each other s**t" all the time.
The 'Can't Fight the Moonlight' singer and her husband are set to appear in a new reality series for VH1, and say it will show how their relationship is more fun than people realise.
LeAnn told UsMagazine.com: "There's a lot of heart to it but there's also a lot of laughs. Eddie and I are very much that way in our relationship. We have a lot of humour between the two of us and give each other s**t a lot, so you see that."
The couple met in controversial circumstances, as Eddie was married to reality star Brandi Glanville at the time, but LeAnn says their day to day life is much less dramatic than people imagine.
She added: "People read about us constantly and it's so opposite of who we are.
"I think people really think we take ourselves seriously. It's so opposite of that but no one ever gets to see it.
"Other than the reason of us wanting to work together and be home with the kids, why not have fun and poke fun at everything that's gone on for the last five years."
LeAnn, 31, is stepmother to Eddie's two sons with Brandi, Mason, 10, and six-year-old Jake, but hasn't ruled out having more children with him.
When asked if she would like children, she replied: "Oh yeah! Sure! He's the best Dad already.
"I have a little bit of experience with the kids now so, I feel like I wouldn't be too crazed. It doesn't feel like a real first, first."

Demi Lovato claims sexiness is about being "confident and comfortable in your own skin".
The 'Skyscraper' singer has battled with self harm and an eating disorder in the past, but has arrived at a point where she is confident with her looks.
She told Maxim magazine: "To me, sexiness stems from being confident and comfortable in your own skin."
When asked what her best attribute was, she added: "My butt."
Demi, 21, also talked about what she looks for in a man, adding: "To get my attention a guy must be genuine, supportive, real, and have the ability to make me laugh."
Asked what her best mental attribute is, the star said her ability for self-improvement.
She explained: "The ability to work at bettering myself - I'm not perfect, no one is, but I'm working at becoming better every day. Every day I can look back and say I'm in a better place than I was yesterday."
While the 'Heart Attack' hitmaker likes to be sexy, she's not too keen to sing about the intimate side of her relationships in her songs as she doesn't want her relatives to hear.
She explained: "Sex is a part of life and it's a personal decision. Some people put it in their music, which is awesome and good for them.
"But for me, there's still that weird feeling in the back of my head that's like, 'All right, I know that my mom and dad are going to hear it and my little sister, and that's really weird for me.' "

Sir Mick Jagger is "looking forward" to performing live with The Rolling Stones again.
The legendary 'Brown Sugar' group postponed dates in Australia and New Zealand after the singer's partner, L'Wrenn Scott, took her own life in March, in order to give him time to grieve.
The band resume touring tonight (26.05.14), performing in Oslo, Norway, and Mick says he's ready to get back on stage.
He wrote on Twitter: "Had a beautiful walk in Frogner Park, Oslo yesterday. Looking forward to the first show! Mick #StonesOslo (sic)"
Alongside the message the 70-year-old frontman posted a photo of him smiling by a fountain.
L'Wrenn took her own life by hanging herself in her apartment in New York, leaving Mick distraught.
In a Facebook message written the day after her body was found, he wrote: "I am still struggling to understand how my lover and best friend could end her life in this tragic way.
"We spent many wonderful years together and had made a great life for ourselves. She had great presence and her talent was much admired, not least by me.
"I have been touched by the tributes that people have paid to her, and also the personal messages of support that I have received. I will never forget her."
The Rolling Stones' 14 on Fire tour will see them appear across Europe until July, then they will perform their rescheduled dates in Australia and New Zealand in October and November.

Amanda Holden thinks Simon Cowell will marry Lauren Silverman and have more children.
The reality TV mogul welcomed his first son, Eric, with the socialite in February and his 'Britain's Got Talent' co-judge is sure he will want to expand his family further.
She told Hello! magazine: "I do [think they will get married]. And I think they'll have more children too, because he loves it.
"Simon definitely should ask Lauren to marry him. He shouldn't let her get away. Lauren's such a good influence on him."
Amanda also thinks the notoriously picky TV star has found someone who will stand up to him in Lauren, and that she is someone who is unlikely to let him win all their arguments.
She added: "He's met his match in Lauren, 100 per cent."
Lauren has previously said she and Simon are in no rush to tie the knot and are simply enjoying parenthood.
The 37-year-old - who was recently granted a divorce from millionaire ex-husband Andrew Silverman, the father of her eight-year-old son Adam - said: "Of course we will get married eventually, but not yet."
Meanwhile, she thinks Eric looks more like his famous father than her, and isn't surprised by how well Simon has taken to being a father.
She said: "I think he's absolutely adorable! He does look a lot like his dad. He looks nothing like me.
"I'm not surprised, I knew he would be an amazing father. He's an amazing guy with a good heart. Sometimes when you get in a situation, you rise to the occasion and he really has. Simon's an amazing dad. It's so cute when I see them together. I just love it."
