Taking to her You Gossip account, Katie Price posted a photograph of the anniversary card Jane Pountney sent to her and Kieran Hayler.
It read: "Can't believe it's been a whole year since we were all on that beach in Nassau… such an amazing day and may you have many more amazing years together."
KATIE PRICE SHARES BABY PHOTO OF PRINCESS
Katie has claimed, however, that Jane sent this card after she began her affair with Kieran.
The mum-of-five wrote angrily: "jane slut Poutney whore gave this to me and kieran a year after we got married knowing she was SHAGGING him! See how she played me too [sic]"
She added a photograph of the front of the personalised card, captioning the image: "This shows how 2 faced Jane poutney in west chiltington ,home wrecker ,is a unloyal friend! [sic]"
Yikes!
Meanwhile, Katie has revealed the secret to her size 8 post-baby body… although it's not what we were expecting.
The mum-of-five, who welcomed her and Kieran Hayler's baby girl into the world on 4th August, insists she's been gorging on takeaway curries and biscuits since she gave birth.
She said: "I'm looking after myself by being healthy in the day - but I can't stay away from the biscuits at night.
"I'm still wearing the size eight leggings I wore throughout my pregnancy under my bump and haven't changed dress size.
"I'm 100 per cent not on a diet."
Katie added: "I'm not breast-feeding but don't think having a baby is an excuse to sit and eat junk food - I've done that before and I know it doesn't make me feel healthy or give me energy.
"However, I still have a chicken korma, rice and naan on a Friday night and proper Sunday roast, too."
But, writing in her column, Katie added that it may have been the stress she was under during her pregnancy - caused by Kieran Hayler's affair with best friend Jane Pountney - that kept her from gaining weight during the pregnancy.
She said: "I know people may be surprised but don't forget, I was under a lot of stress during the pregnancy and didn't pile on the weight like I did with Jett.
"I've also been pregnant for nearly two years, so I think my body was ready to start getting back to my natural size."
