Wow, this feud just took a turn for the nasty.
Taking to Twitter, Katie Price, 34, uploaded a link which directed readers to a close up of the 33-year-old model’s nipple on YouGossip.co.uk, taken when she was on holiday in 2008.
Well, Katie does say in her ‘About Me’ section on her twitter account: ‘Never underestimate the Pricey’.
The tweet comes a day after Kelly Brook made her debut appearance as team captain on Celebrity Juice last night.
During the program, Holly Willoughby and Keith Lemon brought up a comment Katie had made about the model in her Sunday paper column for The Sun.
Katie had written: "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."
When asked what Kelly would say to Katie if she was in the studio with her, the model responded: “What, Magda from There's Something About Mary?”
Not the most flattering of comparisons to make considering Magda was a character known for her bright orange complexion and garish outfit choices.
Kelly has yet to respond to the childish retaliation made by Katie.
Although we have a sneaking suspicion that she may keep schtum after seeing how the Pricey reacts to negative comments.
