Pop star Lily Allen had the Smile wiped off her face - when she ran out of petrol in central London
The singer made a right fuel of herself when her BMW 3-series conked out at the curb side in Park Lane
But she soon cheered up - a helpful photographer stopped taking pictures long enough to come to her rescue
The gallant snapper dashed to a nearby garage and grabbed a fiver's worth of petrol
And lucky Lil was happy to giggle and grin as she refilled her motor before heading on her way
