British pop star Lily Allen is so busy jet-setting she spends the money she makes from her hit records at airports. The moody SMILE singer reveals she shops when she needs to cheer herself up - but life at airports and on planes make her need to spend a challenge. She explains, "I spend my money at the airport. That's where I do all my therapeutic shopping. "Depending on how bad I feel, the more expensive the goods are that I buy. If it's a really bad day, I'll head straight to the watch department. "If I just need to cheer myself up, I'll go buy myself a Clarins lip balm."
