Megan, who fans will recognise from the third series of MTV's dating show, has revealed that Jake had asked her to go home with him after meeting her at a club in London.
Her claims come after TOWIE fans recently watched Chloe confront Jake over rumours he 'slept' with Megan McKenna. He and Megan have both denied this.
According to The Daily Star, Megan hit out at Chloe for being a "mug" when it comes to her former flame, as she believes Jake has been unfaithful to her.
Speaking of her own experience with the Essex boy, Megan told the paper: "We were just having some banter with our friends and then he just turned around and was like, 'When are you going to take me home and f**k me?'
"He was flirting all night. He kept on saying it a few times... At that point I just shrugged it off and I was laughing because I know he's got a girlfriend. I'm not into that."
Megan then added: "I think Chloe is being a mug. Everyone's tweeting her saying, 'Your boyfriend's doing this and this.' I can see it. I've seen him with some older chick in the club, whispering in her ear, trying to take her home and trying to take me home as well."
She warned: "He's done it once, he's going to do it again. A leopard doesn't change its spots."
Megan's comments came before viewers saw Chloe and Jake end their on/off eight year relationship on last night's TOWIE finale.
Chloe finally agreed to meet Jake, after their fallout over rumours he'd had sex with show newcomer (and Pete Wicks' girlfriend) Megan M. Jake continued to deny the claims and told Chloe he doesn't think they should be together anymore.
He said: "I think I'm done as well as you. If you can go around to everyone and speak to everyone before me I don't think that's fair."
Chloe, meanwhile, responded: "It's not fair? Let me tell you what's not fair. You sleeping with Megan isn't fair... You are a liar! You have broken me."
Megan R appeared to be watching the confrontation between the now ex-couple and liked several tweets hitting out at Jake on Twitter. One read: "I believed Megan until I seen how sh*t Jake is at lying, GUILTYYYYY #towie."
Another was posted by Chet Johnson, it said: "That is one way u don't treat a woman she needs to just dump him and never talk to him again."
Jake hasn't responded to Megan R's claims about him. Reveal has contacted a rep for him for comment.
