It's nothing to "Smile" about - 22-year-old British pop singer Lily Allen was arrested for allegedly attacking a photographer back in March. Lily was leaving a London club where she was hosting a party when she allegedly lunged on photographer Kevin Rush and hit him in the face. Lily, who had a pre-arranged time to be questioned at the police station, was released on bail. A Scotland Yard spokeswoman confirmed that the pop star was "arrested in connection with an allegation of assault. She has been bailed to return on a date in late July."
