The war between Tamra Barney and her ex-husband Darren Vieth is far from over, and Darren says he wants to confront his ex-wife on TV to prove she's lying about him.

Darren is threatening to call into Bravo's Watch What Happens Live Monday night (tonight) to confront Tamra in front of Andy Cohen in order to get to the bottom of why she called him out for cheating on her during their marriage — with another man! Tamra just so happens to be a guest on tonight's episode.

"I have nothing to hide," Darren said. "Let's get to the bottom of it on the air. I'm more than happy to call out Tamra about her lies on TV."

Tamra unleashed her fury on Twitter last week, claiming that Darren was making up stories about her and being paid for it — right before she called him out on his supposed homosexual encounter. "The stories people make up when they are broke," Tamra wrote on Twitter. "My heart goes out to my ex. His children don't speak to him and his 3rd wife left him."

She also posted a text from her ex-husband on Facebook but has since deleted it.

She most recently addressed the matter in a more subtle way, posting a photo of a quote which reads, "I don't know what's worse: People who lie or people who think I am stupid enough to believe the lies!" along with the message, "You know who you are!"

But Darren sticks by his innocence, saying, "I want her to tell the truth. And I’m going to sue her for saying I cheated on her with a man."

We'll have to see how this one plays out!
