Amy Winehouse Shows Off Pearly Yellows

Singer Amy Winehouse flashes a smile in a cab on the way to rehab in London, England on Saturday.

Amy, 25, traveled with her friend Blake Wood.

The mischievous British singer was supposed to meet with the police on Wednesday with regard to her alleged punching of a fan last month. After asking for an autograph, Serene Flash alleges that Amy punched her in the face. Unfortunately, the Rehab singer didn’t show up for the hearing and could be facing additional disciplinary action.
