Without her often outrageous outfits, headdresses, hairpieces and flamboyant stage personality she is down to earth, friendly and talks frankly about her life and career.
Lady Gaga--her friends call her Steffi--- feels she is now a big enough star to confess to me one of the secrets that has boosted her career------when anybody advises her to do something, she says she always does the opposite.
"Before my first single and music video ever came out it was suggested I should get a nose job but I said 'no.' I'm proud to be Italian and I love my Italian nose. I didn't always but I had learned to love who I was," she says.
"If people wanted me to look like a sexpot I would look like the opposite. If they said 'try dancing and looking this way' I would always flip it on my head and do it my way.
"That way I maintained my authenticity and maintained who I am. I was not the prettiest girl in the room, I was a little weird and I liked being weird. I didn't like to be sexual in a way that other pop stars were. I was my own thing."
She is confiding her secrets as we talk in a suite at the Royal York Hotel in Toronto before the premiere of her much anticipated movie A Star Is Born, which is directed by and co-stars Bradley Cooper.
She is being tipped for an Oscar nomination for her role as Ally, an aspiring singer discovered by Cooper's Jackson Maine, a country music star struggling with drug and alcohol addiction. As her career takes off his demons threaten to sabotage their happiness.
For the role 32-year-old Gaga made an exception to her rule and completely trusted Cooper and what he told her.
A Star is Born, Cooper's directorial debut, is the fourth remake of the story and for it Gaga had to abandon her real self as that girl from New York's Lower East Side who spent hours doing her makeup before her gigs and instead let the camera zoom in on her wearing little or no makeup.
"It put me in the right place I needed to be," she says. "When my character talks about how ugly she feels---that was real. I'm so insecure. I like to preach but I don't always practice what I preach."
