Lady Gaga discusses everything from her first kiss to hearing Bradley Cooper sing for the first time as she appears on “The Ellen DeGeneres Show” Thursday.

The 32-year-old, who has been busy promoting her latest film “A Star Is Born”, took part in a game of “Ellen’s Burning Questions” on the show.

DeGeneres, 60, wastes no time in quizzing the singer on her first celeb crush (which is Adrien Brody, FYI) and her very first kiss.

Gaga explains: “I think his name was Austin, I was at camp. [I was] 14.”

The skit also sees the musician admit she sleeps in “nothing” at night.

Gaga, who plays Ally in “A Star Is Born”, later discusses bonding with Cooper, who stars as Jackson Maine, in their much-talked about flick.

The “Born This Way” hitmaker says of hearing the actor sing, “I was just extremely humbled by the experience of meeting Bradley and him coming to my home, he makes you feel comfortable right away.

“Before I knew it I was heating up leftovers in the kitchen and we were talking about life and then we started to sing together at the piano.

“I heard his voice and I stopped dead in my tracks and said, ‘Oh my gosh Bradley, you can sing!’ He sings from his soul.”
