Pop singer Lily Allen donned her dark hair extensions again for a special night on the town with her beloved Grandad. Splash snapped the starlet as she left the English National Ballet's Christmas Season at the Coliseum, though unknowingly to the star she appeared to be sporting some odd gray roots!  Lily reportedly avoided the after party at Bungalow 8 after having a row the day before with the owner. Instead she took her Grandad to The Ivy for dinner.
