"For me, Kate Moss is the ultimate celebrity," he said. "A friend of mine had one of Kate's basques.
"He gave it to me and I DNA-tested it just to discover her genetic ancestry Scottish apparently. Nothing more," he said.
Bizarre though this may be, this is not the case of the obsessive stalker that it appears.
Fred Vermorel, 55, a part-time art history lecturer at Kingston University, is actually the author of Kate's unofficial biography "Addicted

He is tight-lipped about how he did this but it proved informative.
He said: "Pete has a whole suite of rooms at that house. I knew they hadn't broken up during the cocaine scandal because his furniture was still there and his Jag was always parked in the
