Pop pauper Duffy

Duffy hasn't made any money since she started singing.The 'Mercy' singer - who is proving a hit in both the UK and US - admits she hasn't seen any of her earnings yet, but isn't worried about her lack of funds.She said: "I haven't had any money yet! I think it's something to do with royalties. But at least I have enough money to buy a pair of tights now!"I don't care about the money, I don't do it for that. I do it because I can't not do it. I have a love-hate relationship with music. It drives me mental but if I'm not writing melodies and lyrics I feel ill."Duffy, 24, also claims she has made a conscious effort not to let her growing fame change her life.She added: "I'm clinging onto reality. I still want to hang out with my friends and have a drink but I don't have any time. Sometimes it does my head in. But I wouldn't have it any different."
