In fact, according to Richards, her hubby doesn’t know that she revealed on Andy Cohen‘s SiriusXM channel Monday that she lost her virginity to her first boyfriend C. Thomas Howell, who recently starred on Bravo’s Girlfriends Guide to Divorce.
“I have not talked about this with my husband, I just hope my husband is so busy in meetings today,” Richards, 46, told PEOPLE Now of whether she and Umansky had discussed her recent confession.
According to the Real Housewives of Beverly Hills star, the only reason she even admitted the intimate detail in the first place was because she felt comfortable in Cohen’s radio studio.
“Because I don’t talk like that, or think, or you know – I would never even talk like that, but Andy … you know, you’re in the booth, you have the little earphones on, you feel like you’re in a quiet … just the two of you,” explained Richards, 46.
Richards said she told Cohen, 47, not to ask that question, but the Watch What Happens Live host convinced her it was fine since “it was 100 years ago.”
“And I said yes and next thing I know, people are sending me pictures [of me and Howell]! I was like, ‘Great!’ ” Richards said with a laugh.
