The 29-year-old has reportedly been dating Aussie jewellery designer Juliet Bakos for five weeks, but judging by Kelly’s latest text messages she is NOT happy about his new romance.
David shared a screen grab of text messages on his Twitter which he claimed were from Kelly, writing alongside it: “Stop insulting the woman I’m with! People need to see u for how u are a nasty bitter woman (sic).”
In the messages, Kelly appears to refer to Bakos as ‘actually fat’ before telling him: “As long as she is buying you *** and you can have a place to stay all can be overlooked…lol.”
The text then read: “And Jess is a little s**t,” referring to Ex On The Beach star Jess Impiazzi, who David was also recently linked to.
In further messages Kelly, 35, also appears to call Big Brother star Aisleyne Horgan-Wallace a ’s***k’.
A friend of David’s told The Sun: "Kelly said even more offensive things to David but for Juliet's sake he didn't make them public. He doesn't understand why Kelly is even interested in his life any more.
"She is the one who dumped him, then begged him to come back, only so she could dump him again.
"For some reason she hates the thought of him with other women but doesn't actually want to be with him."
Kelly and David split at the end of 2014 after nearly a year together.
The former Big Breakfast star is now living in Los Angeles where she is filming new sitcom One Big Happy.
