The Kooks frontman LUKE PRITCHARD has slammed Lily Allen for cutting short a recent US tour citing exhaustion. The Smile hitmaker claimed she was too tired to continue live performances last month (Apr07) and also confessed she was missing family and friends. But Pritchard has branded the excuse feeble and questions Allen's commitment to her career. He says, "How hard is it playing your music and having people asking you about yourself? That's what it's all about. "We were on the road for two years and I'd never say it was hard work. It's tough, especially in America, but it's fun. And when you hear people singing your songs, knowing all the words, it's amazing."
