The reason Amy Winehouse has been pictured with a swollen cheek over the past few days is because she put a cigarette out on it, The Sun reports. Apparently, Amy was repeatedly asked to put her cigarette out at a London restaurant because of the smoking ban, and horrified other diners by stubbing the cigarette out on her own cheek. A source tells the newspaper, "She hardly flinched because she was so high. The whole place was open-mouthed in horror." The Sun says that the wound has become infected because of Amy's attempts to cover it up. However, a representative for the singer has previously said that Amy is suffering from the skin infection impetigo.
