'The Secret World of Johnny Depp', penned by celebrity writer Nigel Goodall, suggests the heartthrob actor enjoyed dressing as a woman so much while filming transvestite drama 'Ed Wood' that he continued to wear female undergarments off camera.
'Ed Wood' director Tim Burton and the rest of the cast are said to have been left baffled by Depp's lingerie obsession.
The book says: "Depp developed a weird habit where he would grab the little hairs over his nipples and just try to twist them around, absentmindedly, while he was pacing around in women's underwear." In the book, Goodall also claims the heartthrob actor, who has two children with his long-term partner Vanessa Paradis, once fell for a woman because of her sweater.
The book quotes Depp as saying: "I love angora sweaters. Oh man, they're unbelievable. They really feel good. This girl I dated when I was a teenager, she had an angora sweater. When we broke up, I was upset, but not about her. It was the sweater."
