The Real Housewives of Beverly Hills star stopped by to chat with the Bravo mogul on his SiriusXM channel Radio Andy and she spilled the beans about a former famous flame.
"Well, you know that my first boyfriend was C. Thomas Howell, for five years. Like, a serious boyfriend for a long time," the brunette dished when asked about her love life.
"I got married so young and had my kids so young, so that was the only actor. That's a good one. It was my first kiss, my first boyfriend, [for] five years."
Cohen then interjected and asked if that meant that Howell was her first, um, lover, and she immediately broke out into a nervous giggle.
"Oh my god, this is so awkward. I'm so glad my husband isn't here right now," Richards exclaimed during the radio program.
"He says I wasn't born until I met him, [that's] what he likes to say."
Cohen then pried a bit more and asked how long the young couple waited before having sex, but Richards wasn't having any of it.
"No, uh-uh! I have four daughters," she answered before adding (slightly sarcastically, mind you) that the duo waited "many, many, many years…A week before we broke up."
Way to handle the tough questions with equal amounts of class and a sense of humor!
