Real Housewives star Teddi Mellencamp claims she had a one-night stand with Matt Damon

Former Real Housewives of Beverly Hills star Teddi Mellencamp has opened up about her secret tryst with the Hollywood actor.

Tamra Judge is outing some of BFF Teddi Mellencamp’s sex life secrets – including one involving Matt Damon.

The Two Ts in a Pod co-hosts appeared on SiriusXM’s Jeff Lewis Liveon Tuesday, where Judge forced Mellencamp to open up about her one-night stand with the Air actor 20 years ago.

“She mentioned it on a podcast, and then went back and told producers, ‘Take that guy’s name out,’” Judge, 55, told host Jeff Lewis, as reported by Page Six.

“And so now, I tell people, ‘If you guys wanna know, just DM and I’ll tell you who it is.’”

“She tells people on the DMs. I’m like, ‘Stop telling people,” Mellencamp, 41, joked. “I did not want to out this guy. Who knows?!”

However, Mellencamp went on to explain that she snuck into a club with a fake ID at just 20 years old to meet the hunky actor.

“He was probably 30 – 10 years older,” the Real Housewives of Beverly Hills alum explained. “I only slept with him one night. He didn’t get my number.”

Although Mellencamp started off just giving hints about his identity – such as the fact his initials are “MD” and that he “has a very famous best friend” – a producer quickly guessed it was Damon, 52.

“I’ve already been coined a liar, I don’t need these kinds of things out and about,” she joked as Judge erupted into a fit of laughter.

Despite her alleged one-night romance with Damon, Mellencamp went on to marry security manager Edwin Arroyave and the pair welcomed four children.

Meanwhile, the Good Will Hunting star wed Luciana Bozán Barroso in 2005. The pair share two daughters.

In fact, it appears the A-list actor prefers to meet his partners out on the town as he met Barroso while she was working at a bar in Miami in 2003.

Reps for Damon did not immediately respond to Page Six’s request for comment.
