Cooper was interviewing Gaga for a 60 Minutes profile and he ended up drinking more whiskey than he could handle.
“She insisted that we do the interview at a bar and drink Jameson,” Cooper said.
“I don't drink, so I drank this glass of Jameson, which I had never had before, and I had to stop the interview like midway through because I was drunk. I mean, I had no idea what I was asking her.”
When the interview aired, it unfortunately didn’t show any candid clips of Cooper.
Host Andy Cohen asked Cooper if he had ever had a similar experience while conducting an interview.
"[Celebrities are] generally less impressive in real life than you think they're going to be…but like, Madonna is a hard interview because she's been interviewed so many times," Cooper said. "You're trying to do stuff that won't bore her and she'll tell you when you're boring her, she'll be like, 'OK, that was a really stupid question.'"
