British pop star Lily Allen has reignited her feud with Madonna, insisting people only buy the HUNG UP star's records because she's so famous. The SMILE singer criticised the pop queen last August (06), saying, "She might have meant something once but I don't know many people my age who care," and now she's lashed out at her again. She says, "I never say anything unprovoked but an interviewer asked me who, in my opinion, was the most overrated pop star. And overrated for me is someone who sells a lot of records because of who they are. And I don't think people buy Madonna's records because they think they're really good."
