11:34 AM PT -- Jen Harley is firing back at Chad's claim that she knew exactly what she was doing when she made out with him in Vegas ... again insisting, in her own words, that she had too much booze for her own good ... and wishes she could take it back.
Jen tells TMZ ... she absolutely would NOT have kissed Chad if she was sober, and not only that -- but she says she had no idea his friend was recording them the whole time, something she finds incredibly shady.
Jen also says she knew the lap dance video -- which was up on her IG story for a bit -- was going to get out, but the fact that Chad's buddy was feeding his own clips to the media ... she says that ain't cool, adding she regrets the whole situation.
As for the allegation that her manager was simply doing damage control for her ... Jen tells us that's not true either -- she insists she dictated a statement to be sent out, so it was pretty much coming straight from the horse's mouth.
No word from her on how this might impact things with Ronnie, but it sounds like Chad's planning to deal with that himself.
Chad Johnson says Jen Harley's making him look like an a**hole after their Vegas hookup, which he claims is unfair ... but he also wants to squash any brewing beef with her ex, Ronnie Ortiz-Magro.
The former 'Bachelorette' bad boy was leaving the gym Monday night in the San Fernando Valley when he addressed the fallout from the video of him making out with Ronnie's ex ... specifically, Jen alleging she was plied with booze and set up.
Chad says that's "crazy ridiculous" and claims Jen admitted to him, her manager made up the "set up" story to help her save face ... but he says he's getting screwed in the process.
Chad's pretty adamant it was just a wild, fun night in Sin City and Jen knew what she was doing -- so he wishes she would just come clean.
At the same time ... Chad feels like he needs a sit-down with Ronnie, with whom he used to be bros, and says he WILL talk to the 'Jersey Shore' star. Even Chad can admit making out with a friend's baby mama is a "major f**k-up on my part."
Sounds like Chad should work on his apology a little bit before he makes the call, though ... because he's still coming off as a guy who believes he's been victimized.
Put yourself in Ronnie's shoes (scary, we know) and watch.
