Lady Gaga's parents heard "everything" she said growing up, as there were no doors in their home.

The American songstress and younger sister Natali were brought up their mother and father Cynthia and Joseph Germanotta in a New York apartment on Manhattan's Upper West Side.

Gaga says her home was very open, and as a result she had very little privacy growing up.

"My parents' room and the one I shared with my sister were on the top floor. There are no doors on the bedrooms," she explained in an interview with British newspaper The Sun.

"My parents could hear everything me and my sister said growing up. And I heard them too!"

Gaga still stays at her family home from time to time. The outlandish star has a hectic schedule which means she is often on the road and doesn't have her own base.

"I love being with my parents, but I also really fear domestication," she revealed.

"I just don't have a home. I stay between my friends' places and my parents'."

Gaga performed at New York's Madison Square Garden over the weekend. The singer joined stars including Flo Rida, Kelly Clarkson and Gym Class Heroes at the festive Jingle Ball.

She performed a number of her hit songs at the seasonal bash before belting out Bing Crosby's Christmas classic White Christmas.
