On the 'Late Show,' Anderson Cooper told David Letterman his mother, Gloria Vanderbilt, has had some pretty impressive boyfriends in the past. And she wasn't shy about letting her son know.
"My mom does not, like, she has no filter. We'd be watching a movie when I was a kid. I remember watching 'On the Waterfront' with her, and I'd be like, 'Did you know Marlon Brando?' And she'd be like 'Oh yes.'"
Yes, Gloria, who's now 90 years old, dated the likes of Frank Sinatra, Clark Gable and even Marlon Brando.
Anderson told Dave that Gloria and Carol Matthau, who later became Walter Matthau's wife, both saw Brando in one of his movies and vowed to hook up with him.
In Anderson's words, "Carol was the first one to do it. And then she set it up for my mom." You go Gloria!
This isn't the first time we've heard about Gloria's past romances, though.
She outlined thirteen of her greatest relationships in her book, "It Seemed Important at the Time: A Romance Memoir."
And she raved about her time with Frank Sinatra in an interview with CBS back in 2004. "He came along and ring-dinged his way into my heart ... and he just - you know - was a lot of fun, very romantic."
