British singer Lily Allen refused to take part in Bob Geldof's latest Band Aid single because she fears the charity project comes across as "a bit smug".
The Smile hitmaker reveals Geldof asked her to take part in the latest recording of Do They Know It's Christmas?, but she turned down the offer as she felt she didn't fit in with the "success club" of stars.
Allen insists she is happy to give a donation to charity, but didn't want to join singers including One Direction, Sam Smith, Bono and Ed Sheeran in the studio.
She tells Britain's Event magazine, "I got an email asking me to do (Band Aid). Well, I'm not on it am I? It's difficult to give an explanation why I didn't do it without sounding like a complete c**t. I prefer to do my charitable bit by donating actual money and not being lumped in with a bunch of people like that. It's the success club and I'm not really in that club. I don't think I'm above it at all - I'm way below it. But there's something a bit smug about it. I don't care if Bob's got the hump with me. I actually don't mind Bob. He doesn't give a s**t and he's grumpy like me."
The charity anthem, which is raising money to help Ebola sufferers in West Africa, became the U.K.'s fastest selling single of the year (14) following its release on 17 November (14).
