Josie Cunningham recently revealed she is desperate to buy Katie Price's breast implants, which the mum-of-five is auctioning off for charity.
The Leeds-born model said: "OMG I'm deffo going to be bidding on @MissKatiePrice boobs! I've got the most famous tits in the country only fair I have the 2nd as well.
"I'll be the first one bidding."
KATIE PRICE: "I'LL SELL OFF MY OLD BREAST IMPLANTS FOR CHARITY"
But, when 36-year-old Katie was asked to comment on Josie's wish, she decided instead to focus on the mum-of-three's underwear choices.
Looking at a recent photograph of Josie flashing her underwear on a night out, Katie said dismissively: "Look at that bra."
Which really upset Josie, who angrily revealed that she had purchased said bra to be just like Katie.
KATIE PRICE: "I'LL HAVE MORE KIDS IN MY 40S – KIERAN BLINKS AND I'M PREGNANT"
"F*ck you! MissKatiePrice ! "Look at that bra!?" -I actually bought that because I WAS a fan of yours & was closest I could get to ur range!" (sic) she tweeted.
"I was a massive fan and never slated you even after your first and second horrible article about me!"
Posting a photograph of Katie wearing an admittedly similar bra, she added: "I was a massive fan and never slated you even after your first and second horrible article about me!"

Which is, as many of you may remember, not exactly true; after all, Josie did famously offer her sympathies to Kieran Hayler for getting his wife pregnant.
And, of course, there was the time that she insisted that Peter Andre's new partner Emily MacDonagh was a better role model than Katie ever could be.
Perhaps it is for these reasons that Katie has yet to respond to Josie's latest comments.
