Since Megan's been in the CBB house, Jordan hasn't held back when it comes to talking about her, and has already branded her a "nasty piece of work." He claims Megan lied to him about signing up for the Channel 5 reality show and has now said he "gave up everything" for their relationship to work.
Speaking to The Daily Star recently, Jordan continued his tirade against his ex, insisting Megan will do anything to further her own career.
"Megan's not a nice girl at all. She's nasty, jealous, selfish and money-grabbing," the Ibiza Weekender star said. "She's completely betrayed me and she'll do it again"
On CBB, viewers have watched Megan strike up a bit of a romance with Geordie Shore's Scotty T, however, Jordan has claimed it is all part of her game plan.
He continued: "Megan used me to get famous and I gave up everything for her, then she dumped me. She only cares about herself. Scott should be careful."
"Megan knows how reality TV works and she wants to be the major storyline," he added. "She has no respect for me, jumping into bed with Scott so soon after."
Jordan and Megan dated for over six months, after meeting on the third series of Ex On The Beach. The pair had seemed pretty loved-up and had even talked about marriage, with Jordan moving to Essex to move in with Megan and her family.
However, things didn't work out and while Megan announced she and Jordan had split on good terms in December last year, he claims she broke it off with him "days before she entered the house."
Jordan has publicly said Megan deceived him by lying about Celebrity Big Brother.
He claimed the starlet signed up to the show behind his back and had only planned to break up with him, if she secured a place in the house.
"She was denying to CBB bosses that we were together," he said. "I only found out she was going on CBB when the lineup was leaked, I found out the same time as the rest of the UK and she still denied it!"
However, Megan's rep has hit back at Jordan's claim, insisting she went about things professionally, as she was legally obligated to keep her place on the show confidential.
They said: "All contestants have to agree to complete confidentiality about meetings to discuss becoming a participant on CBB and Megan simply behaved professionally in not disclosing any information about her appearance prior to Channel 5 broadcasting the first show as she had signed a legally binding confidentiality agreement."
Her appearing on the show has definitely left a sour taste in Jordan's mouth, after he claims he gave up everything for the pair's romance.
"I've slept with over 700 birds, but Megan made me want to give that single life up for her. So I gave up everything. I was known as being a single party boy and gave up my Magaluf business for her and moved away from all my friends. She didn't do anything for me. She made no effort... I spent years building up my career and gave it all up for her and showered her with thousands of pounds worth of gifts."
Now, though, Jordan is enjoying being single again and admits he hasn't "exactly been innocent" since their break-up. He confessed to already moving on with Megan's friend and slotting back into the party boy he was known as before.
Jordan has also eyed up his Ex On The Beach co-star and Scotty T's ex Ashleigh Defty, admitting he could be tempted to date her just to annoy her famous ex-beau.
"Ashleigh's hot, so of course I'd take her out," he revealed. "If it annoys Scott all the better."
While Megan is unaware of Jordan's comments about her recently, her best friend Chloe Meadows has jumped to her defence. Hitting back at Jordan, she exclusively told Reveal: "Jordan is so bitter at the moment. He is so, so bitter. The things he is doing and the things he are saying - I think, personally, he is just embarrassing himself."
She added: "Megan is obviously not going to like it when she hears."
