Friends and family gathered at an emotional funeral service for Amy Winehouse in London on Tuesday, after which the singer will reportedly be cremated. Kelly Osbourne and Mark Ronson were among those in attendance. Reg Traviss, Winehouse's boyfriend of two years, did not attend the service, though he had spent time with her in the days leading up to her death. In an interview with The Sun, Traviss rejected rumors that she had died in a drug-riddled haze. "She has been full of life and so upbeat recently, exercising every day and doing yoga," he said. "This terrible thing that happened is like an accident." Winehouse's ex-husband, Blake Fielder-Civil, who is currently serving a 32-month jail sentence and has been blamed for introducing her to hard drugs, was not in attendance. Though Winehouse's family reportedly believes she died of a heart attack or seizure, her cause of death will not be officially released until October.
