UPDATE: A thorny situation has gotten worse as Tamra Barney's first husband is now challenging Tamra to take a lie detector test and is threatening to take legal aciton. 

After Tamra claimed that first husband Darren Vieth was slamming her as a liar and bad mother because he wants money, Darren denies that money had anything to do with it.

“I’m not broke, and I never asked anyone for any amount of money for a story,” Darren tells Radar Online. “Nor do I want any money. I would turn down money if it was offered. I came forward because she blamed me for her suicide attempt."

“This is about the truth,” he says. “So now I challenge [Tamra] to a polygraph to settle who is telling the truth.” Strong words!

Earlier today, Tamra tweeted that Darren "cheated on me with a man," which Darren says is untrue. 

"I’m straight, I’ve never cheated, and I’m going to sue her for these statements," he adds. "All I want is to have a relationship with my son, and she spoiled that."

Original story: Tamra Barney's first husband has some not-so-flattering things to say about the Real Housewives of Orange County star — and she doesn't appreciate it.

Darren Vieth, who got divorced from Tamra in 1990, is upset by Tamra's claim that their split led to her suicide attempt and is unloading on the reality star.

"Tamra is a liar, a cheater and a bad mother to our son, Ryan, and she seemed to enjoy constant drama in her life because it lead to attention,” the 48-year-old Darren tells Radar Online. “I couldn’t believe that she blamed our failed marriage for her first suicide attempt."

Darren accuses Tamra of cheating on him, saying he caught her early on in their marriage in their house with another man.

A man “about twice my size answered the door,” Darren says. “I told him I wanted to speak with my wife. He told me, ‘Tough luck, she’s with me now.’ Tamra was standing behind the guy, snickering and laughing at me.”

Darren says Tamra moved out a week later and took Ryan with her. But Darren says that when he started dating someone almost a year later, Tamra begged him to take her back.

“I flat-out refused,” Darren says. “One day, Tamra called me and said, ‘If I can’t be with you I’m going to kill myself.’ I tried to talk her out of it, but she said, ‘This is going to be my final goodbye to you,’ then hung up.”

Darren says he quickly informed authorities, who rushed Tamra to the hospital where she was treated. 

Then, Darren says that, a week before he was to get remarried, Tamra left their then-nine-year-old son, Ryan, on Darren's doorstep with a garbage bag full of clothes. "She said to me, ‘Here, you raise him’ and left," Darren says. Darren says he had "sole custody" of Ryan for several years, until Tamra's second husband Simon Barney came into the picture.

Wow! Talk about some heavy accusations. But Tamra is saying that these claims are untrue. She calls it "all trash" and denies that she cheated on Darren and was a bad mother to Ryan or gave up physical custody.

"The stories people make up when they are broke," Tamra tweeted on July 18. "He has no one  Ryan does not speak to him, and his wife just left him."

"He cheated on me our whole marriage, and now he wants press," she continues about Darren. Tamra adds that Ryan told her about Darren, "Mom, feel sorry for him  this is why his life is shit."

Yikes. It doesn't sound like Tamra and Darren will be patching this up anytime soon.
