A US journalist has revealed that Lady Gaga got him drunk during filming for an upcoming profile on the singer.

Anderson Cooper followed the star over a series of months for the 60 Minutes feature, due to air next February.

In an interview with The Insider, Copper recalled one interview in a London pub where he drank so much that he was no longer able to ask any questions.

"We actually ended up that day in a pub in London drinking Jameson (Irish whiskey), which I don't really drink," he said.

"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 any more questions."

Cooper recently filmed a much-talked about 60 Seconds interview with Eminem, which aired earlier this month.
