Lily snapped on the paps.

Lily Allen lost her “Smile” as she was photographed kicking and attacking a snapping photog who allegedly chased her down a London road on Thursday.

The 23-year-old singing star leapt from her car like a raging bull, swinging punches and throwing bottles at the paparazzo, before being restrained by her own bodyguards.

No criminal charges have been filed.
