In a new interview, the Ex On The Beach star has described Megan as a "nasty piece of work".
In quotes printed in The Sun On Sunday, Jordan claims Megan broke off their relationship to appear on Celebrity Big Brother.
Jordan accuses Megan of "acting like a s***" in the CBB house and says: "She's a nasty piece of work who totally deceived me. All she cared about was her career and being famous."
However, a spokesperson for Megan denied the claims, accusing Jordan of "malicious lies" and of being a "consummate storyteller".
They responded with a statement saying: "Megan ended the relationship for numerous reasons, not least because her ex is a consummate storyteller and was obviously more interested in the idea of fame than being a real man. His immaturity and insecurity became more and more apparent and this story simply confirms that her instincts and her decision were 100% correct.
"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.
"As Megan now cannot respond directly to what are simply malicious lies I feel I must set the record straight both for Megan's integrity and that of CBB. This is a desperate publicity seeking exercise on his part."
EOTB stars Megan and Jordan, both 23, began dating in April and had even talked of marriage.
But things have clearly turned very sour for the former lovebirds...
Just days ago, we told you that Jordan had warned Megan's CBB housemate Scotty T to stay away...
According to reports (again in The Sun), Jordan will NOT be happy if Geordie Shore's Scott and Megan end up getting together.
A friend of Jordan's told the paper: "Jordan has the same behind-the-scenes team as Scott and told them to make sure he knows how explosive things could get if he goes near Megan.
"Jordan's not going to be happy if Scott and Megan get together... and he will be out for revenge," they warned. "But that won't put Scotty T off."
Sounds like we haven't heard the end of this feud...
