Vicki Gunvalson: "Done" With The Real Housewives of Orange County? >>Hollywood

On next week's reunion special, Vicki Gunvalson claims she's "done with the show," but is she really leaving The Real Housewives of Orange County?

Apparently, tension between the cast members and Vicki over her on-again off-again boyfriend Brooks Ayers finally boils over on next week's install ment.

"Guess what, Vicki's done with the show!" Gunvalson proclaims as she walks off the set of Monday's climactic part three of the reunion special.

Next week, Vicki, Brooks Ayers, and her daughter Briana Wolfsmith-Culberson all let the vitriol fly, and it gets quite epic, even by RHOC standards.

In one instance of dueling tempers, the unpopular Brooks and Briana go at it, as her husband Ryan's antics are brought up and she says to Vicki's love interest:

"Don't you dare make s**t up about my f***ing husband!"

"Don't make s**t up about me!" Brooks shoots back.

Ayers, of course, has been in the news a lot lately.

Whether they're making it up or not, he's accused of plotting to have his business partner killed ... and for calling Vicki a "f*cking whore" on tape.

Listen below to leaked audio of him threatening to "beat her ass," and bragging that he's free with his hands "because … that's what we do in the South."

Should be a fun reunion Monday ...
