Eddie Cibrian Breaks Silence On Ex-Wife Brandi Glanville's Bombshell Claim He Had Affair With 'Cave' Costar Piper Perabo

Real Housewives of Beverly Hills star Brandi Glanville came forward with some explosive allegations in a new interview, claiming Yellowstone actress Piper Perabo and her ex-husband, Eddie Cibrian, had an affair while filming the 2005 horror-action flick The Cave.

The Bravolebrity revealed why she was not a fan of the Coyote Ugly star after the movie came up in conversation, claiming that she made "friends on set" of The Cave who told her "a lot of things" after she noticed their allegedly flirty banter herself.

"And [Perabo] was a horrible c--- to me," she claimed to Page Six.

According to Glanville, she confronted Cibrian when he returned to Los Angeles after filming wrapped in Romania.

"He convinced me that it wasn't true," she alleged. "We had a 1-year-old son and he was the love of my life at the time and, you know, there was a lot of convincing me of things."

The Drinking and Tweeting author and Cibrian share two children together, having tied the knot in 2001.

They parted ways in 2009 after news of his affair with Perabo's fellow Coyote Ugly star LeAnn Rimes. Cibrian and Glanville divorced in 2010 after nine years of marriage, and the Take Two actor exchanged vows with Rimes less than two years later in April 2011.

"It's kind of ironic that [Perabo] was in Coyote Ugly with LeAnn," Glanville said, before doubling down on her affair claims.
