Kate Moss is selling nicotine patches. The British supermodel, who is desperately trying to give up smoking, is making money on the side by selling the patches.

"At photoshoots, Kate is always getting the nicotine patches out as she usually has to rearrange them depending on what she's wearing for the shots," a source says.

"But if anyone else asks for one, she sells them for ?1.50 (roughly $3). People are very surprised when she tries to charge them for one as it's the last thing you'd expect from a megabucks model."

"But she laughs with it and says it's her little business on the side. The look on people's faces when she says she has to make some spare cash somehow is hilarious!"

The source also says that the 34-year-old is trying to ditch the habit for her daughter 5-year-old daughter Lila Grace, and also because she knows it's bad for her skin. But still, Moss is finding it hard to quit even with the nicotine patches. She can reportedly smoke 30 to 40 a day.

"At 34, Kate knows she doesn't have long at the top left, so has to try and look afterherself better. She has been smoking like a chimney for years, and is finding it extremely difficult."
