Brandi Glanville shared that she found out her and ex-husband Eddie Cibrian’s son Mason lost his virginity after passing by his bedroom door.

“I remember realizing he wasn’t a virgin when I walked by his room and I heard a spanking being given,” the podcaster recalled on Netflix’s “Calabasas Confidential,” which dropped on Friday.

Glanville — who made a cameo on the new reality show’s fourth episode — told her son’s friend Emilie Nelson, “I was just like, ‘F–k my life. My son is not a virgin anymore.’”

The “RHOBH” alum added that Mason, now 22, was around 15 or 16 years old at the time.

“I was crying,” Glanville confessed. “I’m like, ‘I am so uncomfortable right now.’ But at least he’s giving a spanking at least. He’s got some moves.”

The mom of two also took a moment to gush over Mason’s current partner, Sarah.

“I love [his girlfriend]. She’s the best. I want to keep her forever,” Glanville elaborated. “I told her to get pregnant. I was like, ‘Just trick him. Then we’ll have a cute little Irish baby, and I can just watch it.’”

Mason explained that his other half is “the only person” he’s ever dated that he can see a future with.

Along with the model, Glanville and Cibrian also share son Jake, 19.

The exes were married from 2001 to 2010, with their relationship blowing up after Cibrian had an affair with his co-star, LeAnn Rimes, in 2008 while filming the Lifetime movie “Northern Lights.”

At the time, the country singer was married to actor Dean Sheremet.

Rumors of an indiscretion first began to swirl in 2009, with Cibrian initially denying the claims.

In July 2009, both Rimes and Cibrian separated from their spouses just days apart.

The “Take Two” alum’s manager released a short statement after the news broke.

“Eddie is a devoted and loving father first and foremost, and the speed bump he and Brandi are experiencing needs to be worked out privately for everyone’s benefit.” the statement read.

Cibrian and Rimes made their first public appearance as a couple in August of that year.

The “Sunset Beach” actor then went forward with filing for divorce from Glanville.

Rimes officially divorced Sheremet in December 2009.

The “LeAnn & Eddie” alums were engaged a year later before walking down the aisle in 2011. 

Despite Glanville admitting that she once threatened to “murder” Rimes when she found out about the affair, the two have since found common ground.

“We’re like sister wives,” Glanville teased while on the “Hollywood Raw” podcast in 2021. “Eddie’s going to be in my life for the rest of my life. We bicker still like we’re married when we’re not … It’s me and LeAnn and Eddie.”
