It's war! Kelly Brook and Chanelle Hayes in spat over sex with David McIntosh

DESPITE pretty much everyone doubting David McIntosh's fiancé credentials, Kelly Brook has taken the high road when it comes to criticism.

PROUD FIANCEE: Kelly chose to bite back at Chanelle's claims

Well, until now, that is.

The buxom brunette, who got engaged to the muscle-bound CBB star in March, has lashed out at Chanelle Hayes for claiming that her man is a cheapskate.

Ex Big Brother housemate Chanelle today told the Sun that during her three-week relationship with Tornado in 2009, he refused to pay for a Pizza Hut takeaway on their first date, let her shell out for a cinema trip, and denied her the use of his house's heating because it was too expensive.

But when Kelly read Miss Hayes' kiss and tell, she wasn't too impressed, and her perfectly manicured claws came out.

CATFIGHT: Chanelle denied sleeping with David

The 34-year-old tweeted: "Hang on... she slept with him even after he refused to buy her a Pizza? #Shame. I waited for Diamonds."

Meow.

After publicly shaming a fellow female for daring to sleep with a man before he put a ring on her finger, we hoped this tweet wouldn't be left unseen.

Thankfully, we can count on Chanelle to keep an eye on her name when it's popping up on Twitter, and the foxy reality star fired back to deny she jumped in the sack with Mr McIntosh.

The mum-of-one replied: "Haha babe I definitely did NOTTTT sleep with him diamonds or no diamonds. Good luck with the prenup."

She then added: "Plus, you'll regret the diamonds when common sense kicks in hun. #delusional #goodluckanyway #allthebest."

FEISTY: Why is anyone fighting over David?

We thought that was that for the unexpected Twitter spat, but Kelly wasn't ready to give Chanelle the last word.

Regarding her new rival, she tweeted: "She's just trying to make money. Good luck to her. All the best #NoJudgment."

But despite Kelly hashtagging "no judgement" (despite clearly judging her several tweets earlier), Chanelle didn't back down, replying: "Yes MAKING it, not just marrying someone & TAKING it. No judgement right back. It's a shame- thought u were smart."

Clearly not taking lightly to a jibe at her intellect, Ms Brook retaliated: "Feels like I just threw a dog a bone."

Ouch, a saucer of milk for this catty former Big Breakfast presenter.

Seeming to laugh off the canine dig, Ms Hayes finished with: "Well to say I'm shocked a certain "lady" is so b*tchy is an understatement. Awkward would hate to be his most recent ex!"

Ouch – we do love a good Twitter spat, unfortunately we'll have to wait until hunky David gets the boot from CBB to find out his side of the tale...
