Barry Williams, better known as TV’s Greg Brady, was so worried about his psycho girlfriend flipping out on him if he broke up with her, he had to take the entire matter to court. Williams, 50, filed for a restraining order against his girlfriend of three years, beauty pageant contestant Elizabeth Kennedy. According to court documents, Kennedy has a lengthy history of physical and emotional abuse with Williams, and the actor was concerned that his attempts to break things off with her would result in retaliation. She’s threatened to kill him and has even pulled a knife on him during an argument. Yikes!

Greg Brady’s got serious girl trouble.

In court documents posted on TMZ, actor Barry Williams claims his ex-girlfriend once pulled a knife on him and threatened to kill him after losing a beauty contest –- and “The Brady Bunch” star wants a protective restraining order to keep his abusive ex away.

Williams, 50, alleges a string of startling domestic disputes during the past year that grew increasingly violent, but the straw that broke the Brady’s back was when he discovered that Elizabeth Kennedy, 30, had allegedly swiped thousands of dollars from his bank accounts.

“I know that she will definitely try to harm me once she is aware that our relationship is now over,” he writes in the forms filed on Dec. 10 to Los Angeles Superior Court, where he requests a judge order Kennedy to move out.

“I know that if she is given notice she will destroy all of my personal belongings,” he states. “She will rage against me and hit me, she will use any instrument in the apartment as a weapon against me as she has demonstrated her will and capability in the past.”

Williams says that his estranged ex first made the death threats on Aug. 20.

“She was extremely upset about losing a beauty contest and threatened to kill herself,” he writes. “She said she would kill me along with herself.”

They got into a physical altercation on Sept. 25, where, he says, “She started screaming at me about having to move from our apartment –- and without warning, knocked my eyeglasses from my face.”

Then on Nov. 23, he claims, she became violent after accusing him of cheating on her with one of her co-stars.

“[She] ran into the kitchen, went over to the counter and attempted to pull a knife from the knife holder,” he writes. “I caught her from behind –- and she tried to kick me, but missed.

“Elizabeth Kennedy is extremely unstable,” Williams adds. “We have been seeing a therapist.”

He also accuses Kennedy of taking his personal identification number and stealing $29,000 from his bank accounts. His account holder, Wells Fargo, launched a fraud investigation after surveillance video allegedly caught her in the act at ATMs.

The judge granted the restraining order, which rules that Kennedy must stay 100 yards away from Williams as well as move out of their shared apartment. They have been living together for three years.

“This is an unfortunate situation and I appreciate all the good wishes from my friends and fans,” Williams told RadarOnline.com.

Wow, this is way worse than that time that Greg Brady was the chairman of the school cheerleading committee, and had to choose between his sister, Marcia, and that girl who was just dating him to get on the cheering squad! Sorry, couldn’t resist one Brady Bunch reference. But seriously, this woman sounds like a whack-job, and I hope Barry can get himself out of this situation without any further abuse. I wonder if she was always this nuts or did she just snap after losing the beauty pageant? Either way, she’s a hot mess and I don’t blame him one bit for getting the authorities involved.
