Lady Gaga has revealed that she used to hear her parents having sex while she was growing up because their apartment did not have any doors.
The 25-year-old pop queen said that she live with her parents in New York's Upper West Side apartment, and she shared her room with her sister.
"My parents' room and the one I shared with my sister were on the top floor. There are no doors on the bedrooms, Contactmusic quoted Gaga as saying.
"My parents could hear everything me and my sister said growing up. And I heard them too!" she added.
