Debbie Harry worries she sometimes looks like a "sl*g".
The 65-year-old Blondie singer finds ageing tough because sometimes she is concerned about the way she dresses and other times she thinks she looks great.
In an interview with Stylist magazine, she said: "It goes from moment to moment. Sometimes I'm thinking, 'Oh God, I'm really looking good!' And others I go, 'Oh my God.'
"There are some days you feel like you're gorgeous and some days you feel like you're a sl*g.
"Sometimes I do it right and sometimes I do it wrong. Some people get set in their ways, I've always liked experimentation and sometimes my experiments go really wrong - sometimes they go really right!"
Debbie is well known for having dabbled with drugs in the past, and although she is open about her experiences she thinks her use of heroin was a bad idea because it is a "lethal" drug.
She explained: "Heroin is innately and inevitably dangerous - it's lethal."
Asked why she gave it up, she said: "I guess it just wasn't fun any more, you know? It just wasn't fun."
