'60 Minutes' host Anderson Cooper has recounted how he drank Irish whisky with Lady Gaga during their London interview recently.

He said: "We actually ended up that day in a pub in London drinking Jameson, which I don't really drink. So, she got me to drink, like, two of them. And by the end, I was ready to have the interview be over, because I really sort of couldn't ask anymore questions."

Cooper's '60 Minutes' interview with Gaga is set to air on the night of the 2011 Grammy Awards in February 2011.
