It didn't take long for Tamra Barney to find a new man.

The Real Housewives of Orange County star has confirmed that she's dating Eddie Judge, a friend of her estranged husband Simon -- who filed divorce papers to dissolve the couple's 11-year marriage less than a month ago, RadarOnline reported Sunday.

"I started dating Eddie Judge last week. We started hanging out together more after my separation and one thing led to another. We had been friends for over a year," Tamra told RadarOnline.

"We are romantically involved, he is a great guy. It was bound to happen that we both we would dating again after he filed for divorce, it was going to happen sooner or later."

Simon called it "the ultimate act of betrayal" when he learned about the relationship by arriving at Las Vegas' Hard Rock Hotel on Saturday night and seeing Simon and Tamra there together while he was under the impression she was back in Los Angeles.

"I walked in and I saw Tamra with a friend of mine, Eddie Judge. I saw them holding hands and acting like a couple," Simon told RadarOnline.

"As soon as Tamra saw me she let go of his hand and walked away. I went up to Eddie  and asked him if he's (bleeping) my wife.  He didn't say a word. I  couldn't believe what I had just witnessed."

Simon added the incident made him feel "weak" and he fell to his knees.

"The doorman helped me and by the time I had regained my composure they both left to the other side of the club," he told RadarOnline. "I left soon after."

Simon accused Tamra of being "verbally abusive" and having "committed acts of disloyalty and infidelity" when he filed for divorce early last month. She subsequently denied she cheated on him.

Tamra said she's unsure how long her relationship with Judge will last.

"I don't know what the future holds with Eddie and only time will tell," she told RadarOnline.
