Kelly Dodd from the Real Housewives of Orange County has threatened to quit the show after castmate Vicky Gunvalson accused her of taking cocaine on the reunion show.

The first part of the reunion show has not yet aired, but Bravo dropped a preview last week, and fans were shocked to see OG Vicky accuse Kelly of using the illegal white powder.

“I don’t do cocaine, sorry,” Vicky quipped during the pair's heated exchange.

“I don’t do cocaine, either,” Kelly responded. But the damage had already been done.

Kelly hopped onto Instagram to respond to a fan's question about the show.

Kelly wrote:

“I can’t go back if that liar can just say s*** without consequences the money isn’t worth it to me! My daughter means more to me than this [show] and she is trying to ruin my reputation… just out of principle I won’t go back! They can pick the OG I’m out!!”

She also denied taking drugs to another fan and explained why she on't be suing Vicky:

“I don’t do drugs… but I would sue her we sign contracts that we can’t sue each other… it’s ok if she’s on next year I won’t be on.”

Somehow, we don't see Bravo giving original cast member Vicky the boot anytime soon.

The reunion airs this Sunday.
