Brandi Glanville claims her ex-husband, actor Eddie Cibrian, was “f–king” actress Piper Perabo on the set of his 2005 movie “The Cave.” “They did a movie together and [my son] Mason was 1 year old and I went to the set and it was in another country, Romania, I think,” the “Real Housewives of Beverly Hills” alum, 50, claims in an exclusive interview with Page Six. “And [Perabo] was a horrible c—t to me,” the “Unfiltered” podcast host adds point-blank. Glanville says she became uncomfortable at the sight of Perabo and Cibrian’s alleged interactions. Glanville, who married Cibrian in May 2001, notes that she sought out friendships with “The Cave” crew members — and they kept her clued in on what was happening on set. “I made friends on set and I heard a lot of things,” she tells us. When asked about what she heard, Glanville claims she was told “that Piper and Eddie were f—king.” According to Glanville, she confronted Cibrian about the alleged affair when he returned home to Los Angeles after filming wrapped.“When he got home, I’m like, ‘I’m leaving, blah blah, I’m out,’” she recounts.
However, Glanville ultimately decided she wouldn’t throw in the towel — at least not yet."
