Brandi Glanville‘s son’s sex life is apparently not confidential. 

Indeed, the reality star—who shares sons Mason Cibrian, 22, and Jake Cibrian, 19, with ex-husband Eddie Cibrian—revealed the moment she found out her eldest son was sexually active.

“I remember realizing he wasn’t a virgin when I walked by his room and I heard a spanking being given,” Brandi recalled to Mason and his friend Emilie Nelson on the fourth episode of Netflix’s Calabasas Confidential, which dropped May 29. “I was just like, ‘F–k my life. My son is not a virgin anymore.'”

“I think he was 15 or 16,” Brandi continued. “I was crying. I’m like, ‘I am so uncomfortable right now.’ But at least he’s giving a spanking at least. He’s got some moves.”

Yet, the Real Housewives of Beverly Hills alum was very comfortable sharing how much she adores Mason’s girlfriend Sarah.

“I love her. She’s the best,” Brandi said. “I want to keep her forever.”
