British pop star Lily Allen was left red-faced when her credit card was declined at a designer boutique in London. The Smile singer was attempting to buy clothes in the Chanel store in the British capital, but was left unable to pay for the items when her card was rejected. She says, "It should have been a classy moment, me walking into Chanel - but in typical Lily Allen style, I managed to make a pig's ear out of it. "My credit card was rejected, and then when I tried to call the bank the battery on my phone ran out. I was so mortified I left the shop and returned the next day with a cheque."
