Lady Gaga's parents were so shocked by the young star's outlandish stageshow when they first saw her perform in New York, they thought their daughter was crazy.
The pop superstar's mom Cynthia Germanotta agreed to sit down with Oprah Winfrey in the family home and tape a rare chat for an upcoming TV special, and admitted her introduction to a Gaga show at Joe's Pub took her by surprise.
She revealed, "She was in her bikini, performing with Lady Starlight, and decided that night... to actually light hairspray on fire.
"Her father and I were like... he said, 'I think she has a screw loose'."
The interview with Cynthia and her famous daughter will air on Oprah's Next Chapter this Sunday.
