The 34-year-old glamour model took to Twitter this morning, directly messaging the 33-year-old star to say she was sorry for everything she had said about her over the past few weeks.
She wrote: “@IAMKELLYBROOK I'm really sorry for what I've done you know I think your a natural beautiful girl we go back a long way so I'm sorry xx (sic)”
The feuding women came to blows following a comment Katie had made about Kelly’s weight in her column for The Sun newspaper.
Writing about pictures of Kelly in a bikini for a photo shoot, Katie described her as a ‘heifer’.
She wrote: "The pictures of Kelly modelling her latest New Look swimwear range in Miami don't seem to be airbrushed and I'm FLABbergasted to see how big Kelly really is.
"You're a heffer (sic), Kelly, but still a hot one."
Kelly finally responded to the comment during her debut outing as the newest team captain on comedy panel show Celebrity Juice.
When asked by Keith Lemon what she would say to Katie Price if she was with them right there, Kelly responded: “What, Magda from There's Something About Mary?”
Not taking this criticism well, Katie retaliated the next day by posting a close up picture of Kelly’s breast on her Twitter from a picture taken in 2008.
Clearly Katie has now changed her tune and wants the whole school yard argument to be put to bed.
However, after posting a topless picture of her nemesis, it might take a bit more than an apologetic tweet to win Kelly Brook’s forgiveness.
