In last night's explosive interview on The Bachelorette, Jake accused his ex-fiancee of cheating with Michael, which she denied. "There [was] nothing," she said.
Michael says there was something, alright.
"That's a lie," the actor told Us Weekly. "We definitely made out that weekend [June 20] and Vienna made it very clear that it was over between her and Jake."
Girardi said they only danced for less than "nine seconds," but Michael counters: "I wouldn't say we danced for a few seconds. We danced as a group all night."
"We also danced alone for parts of the evening."
Was Vienna Girardi lying about her dalliances with Gregory Michael during last night's tell-all interview - and is Jake's now-single ex seeing the Greek star now?
Michael says she did tell the truth when she told Jake Pavelka that she hardly knew him: "At the time the interview was conducted, we hardly knew each other."
But he took aim at Jake when the former Bachelor star referred to him directly when saying, "That boy told me you cheated when he went on-the-record."
"I never said she cheated," Michael insisted. "I said we hooked up and she said they were broken up. I would never do that if she was in a relationship."
He says he doesn't know anything about Pavelka's claim that Vienna Girardi hooked up with other guys: "I don't know what flings Jake is referring to."
The ABC interview ended with Vienna storming out in tears after Jake raised his hand in anger and stunningly reprimanded her for interrupting him.
