The Ex On The Beach star hit out after Marnie branded him fame hungry and "embarrassing" in her new column for Star magazine,after seeing photos of Jordan and Jem Lucy out together.
Jordan, 23, told Daily Star: "It came without warning and I don't know where it came from. It wasn't long ago we were texting each other about going on holiday together, talking about doing it on the down low."
Geordie Shore's Marnie took a swipe at Jordan and Ex On The Beach's Jem, saying: "I've seen some pictures of Jemma Lucy and Jordan Davies hooking up and all I can say is they get more embarrassing by the day. I don't think you could find two people who are more desperate for fame than this pair. They're a match made in heaven."
Jordan replied via Twitter, saying: "Charming...Funny how you still wanted to go on holiday in secret behind your "on off flings" back #HoesAintLoyal."
A rep for Marnie, 24, had no comment to make.
As for whether Jordan would ever date Marnie in the future, he told Daily Star: "Nah. She is more trouble than she is worth. We had some fun and I wouldn't have said anything negative about her if she hadn't done so about me. She could've at least told me before she stabbed me in the back to get some headlines."
Marnie previously denied denied having romantic feelings for Jordan, telling Mail Online: "He's just my friend. He's like a lovable brother or a gay best friend, except he's not gay. Romantically, I'm not interested. He's just a lovely boy and I enjoy his company."
