He joked: "So what else am I supposed to do? Maybe I'll do an Instagram Live later, I don't know. I got Ben and Housewives cuts to watch. That's what's happening here… And maybe I'll post more shirtless pictures of Anderson."
In 2016, Cooper told the story during an episode of Cohen's Watch What Happens Live.
"Andy and I were first set up on a blind date, which never happened because we had a phone call and after two minutes I said, 'I'm not dating this guy.'
"He broke my cardinal rule … he mentioned my mum within the first four sentences of meeting me."
Since then, the pair has remained extremely close, showing support for one another during trying times, like Cooper's mother Gloria Vanderbilt's death in June last year, and Cohen's recovery from COVID-19 recently.
Both have also become fathers at the same time, with Cohen welcoming is son Benjamin, in February last year, and Cooper announcing the birth of his son Wyatt in April.
Cohen has big plans for their sons to be "best friends" just like them.
In August, Cohen told USA Today that: "We've gotten so much closer since I've had the talk show and since we've been on tour together. I mean we've been friends for 25 years. He's just an incredibly loyal and caring and sensitive and great friend."
For the past three years, the duo has also hosted the New Year's Eve ball drop in New York City, while also conducting their own stage tour AC2: An Intimate Evening with Anderson Cooper and Andy Cohen since 2016.
