"Eat your heart, out Katie! We're stronger than ever!"

That seems to be the message that Kelly Brook wants Katie Price to know as the former unabashedly posted a bunch of photos taken from her recent vacation with boyfriend rugby player Danny Cipriani.

Earlier, the two ladies reignited their bitter word war with the 35-year-old Glamour model Katie warning the 33-year-old TV presenter that her boyfriend "will never be faithful to her."

"Ask Danny about his emails and texts sent to me behind your back which I'll show you. Kieran (Katie's husband) agrees he will never be faithful," Katie posted on Twitter.

The two models share a common denominator, Danny Cipriani, whom Kelly dated from 2008 to 2010 and with whom Katie shared a brief romance in 2011.

The two have been entangled in a weeks-long exchange of barbs after Kelly reunited with Danny in February this year. The bad blood for a while seemed to have simmered down a bit until recent events saw it reaching a new level with more bitter tweets exchanged over the weekend.

The latest bout stemmed from Kelly's apparent mocking of Katie's recent marriage to Kieran Hayler on the TV show Celebrity Juice.

"Did she burn my calendar hanging on his wall?" Kelly said in response to host Keith Lemon's question "What did Katie Price do for her husband on their wedding day?"

When a fan tweeted Katie about Kelly's joke, the mother of three replied: "I'm sure Kelly wouldn't be laughing if I said things Danny Cip said to me about her in the bedroom when I was with him hahaha."

Kelly didn't let the comment pass and hit back by saying that Danny still kept in touch with her even when he was dating Katie in 2011. That time, Kelly was already living with then boyfriend Thom Evans.

She tweeted "No, but I did laugh when he turned up at my house driving your car the next day J I don't think you know anything."

On Tuesday, Katie thanked Kelly for confirming that Danny had indeed driven her car which he supposedly did without a license and insurance. She also teased fans of her upcoming autobiography which will reveal everything about her short affair with the rugby player.

"Thanks for confirming DC drove my car without a license and insurance! Read my auto blog out in October I reveal EVERYTHING xx" Katie posted.

Katie had a brief relationship with Danny in the latter part of 2011, at which time she was estranged from ex-fiance Leandro Penna.

Kelly and Danny, meanwhile, dated for two years from 2008 to 2010. After their break-up, she dated Danny's former Wasps teammate Thom Evans for two years.

In January 2013, Kelly immediately reunited with Danny after splitting from Thom.

The lingering feud between Katie and Kelly started in February this year when Katie commented that the brunette model looked bulkier based on the swimwear photos of her New Look campaign in Miami.

"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," Katie wrote in her column for The Sun,

"You're a heffer, Kelly, but still a hot one," she added.

Katie even naughtily suggested that Kelly must be "comfort eating" because she was again seeing her ex-boyfriend Danny

.Not long enough did Kelly respond labelling the mother of three as being "rude."

"I actually wish her all the best. It's sad isn't it? I think it's a bit sad..."

"I think girls can get away with having a bit of meat on our bones: I don't mind a wobbly arm or a bit of cellulite," Kelly said.

A few days later, however, Kelly couldn't control getting back at Katie via Celebrity Juice. She likened Katie to Magda, the character from the film There's Something About Mary.

When host Keith Lemon asked her how she would react if Katie was with them, she responded: "What, Magda from There's Something About Mary?"

Magda, is the 50-something sun-worshipping character played by actress Lin Shaye best known for her bleached blonde hair and cakey make up.

This angered Katie even more as she posted a photo that zoomed in on Kelly's bare breasts, apparently shot during a holiday in 2008.
