The 32-year-old singer - who is one of the world's biggest-selling artists - has revealed she pretended to be her own manager at the start of her career to try book herself gigs, and Gaga has even admitted to using a fake English accent to boost her chances.

She confessed: "When I started my career, I decided around 19 years old that I was going to go for it as a singer, because I couldn't get any jobs as an actress.

"I just hit the pavement running and I was dragging my piano around New York City banging on doors.

"I would call up and I would be like: 'Hello this is Lady Gaga's manager, she's really hot right now, we would like the 10pm slot for her if you can for her in.'

"I used to just pretend I was my own manager to try and get the best gig that I could."

Meanwhile, Gaga stars alongside Bradley Cooper in the musical romantic drama 'A Star Is Born'.

Bradley, 43, sings in the movie and Gaga has admitted to being shocked by his vocal talents.

The 'Poker Face' hitmaker told 'The Ellen DeGeneres Show': "We're both from the east coast, and we're both Italian, so before I knew it I was heating up leftovers in the kitchen and feeding him and we were talking about life.

"And then we started to sing together at the piano - a song by Creedence Clearwater Revival, 'Midnight Special'.

"And I heard his voice and I stopped dead in my tracks and I said 'Oh my gosh, Bradley ... you can sing.' He sings from his soul. And you now what? He's a great songwriter, he wrote on all of his songs for this film."
