We have a feeling Tara Reid didn't know cameras were rolling during this outburst.

After walking out on a therapy session last week on "Marriage Boot Camp: Reality Stars," the actress starts venting to one of the show's producers in the production office ... who has no idea what she's talking about.

"They only see what Dean tells them because he's a f---ing actor and being happy in front of them," she cries in the sneak peek. "I'm not going to set myself up again. They don't f---ing know the real story!"

Counselors Jim and Elizabeth Carroll watch this all go down from a security feed, but don't want to interrupt because they believe this is one of the few times Reid is being genuine and not closing herself off.

"I don't know what she's saying, but at least she's not censoring herself again," Jim tells his wife in the video.

"I didn't know who anyone was in that f---ing house when I walked in. But everyone knows who I am, everyone, it's a fact," an angry Tara adds, as the producer hilariously tells her, "I don't know 90% of what you're talking about."

She continues going off on alleged beau Dean May, doing nasty impressions of him as someone films her with what appears to be a hidden camera.

Meanwhile, inside the house, May agrees when one of his housemates says Tara is "crazy."
