Troubled British rocker Pete Doherty is sleeping at the thrift store he has opened in London to sell off his junk. The former The Libertines star launched the shop in the Camden area of the city earlier this month (Aug13) to sell a bizarre range of memorabilia including antique storage tins, vintage clocks, lamps, jewellery, and bottles with a handwritten message stuffed inside. The singer/songwriter is even spending time working as a sales assistant at the store - titled Doherty & Martin: The Rag & Bone Collection - and now it has emerged he has also spent several nights sleeping there. A journalist from Noisey.vice.com witnessed Doherty, who is based in Paris, France, asleep with his head on a typewriter at the shop earlier this month, and now the star's business partner, Suzi Martin, has revealed he sometimes stays overnight at the property. She tells NME.com, "He locked himself in the other night to decorate a wall. He drops in and out between preparations for his tour and painting for his exhibition later on in the month." Martin also denied reports suggesting the singer is selling cigarette butts smoked by stars including Amy Winehouse, adding, "(It's a) joke that has gotten out of hand. We don't sell cigarette butts. There are ashtrays all over the shop with (Doherty's) cigarettes in. It's like, if people want to pay 200 quid (pounds) for that, we're not going to say no, but we're not selling them."
