Amy Winehouse is currently in a police station in East London, explaining those pictures from the Sun of her apparently smoking crack.
The Met Police have released a statement:
"She remains in custody. This is in connection with an investigation connected to footage passed to the Metropolitan Police on 22 January."
The Winehouse camp have also shared their perspective:
"She was arrested in order to be interviewed and is co-operating fully with inquiries.
"The interview relates to a video handed to police earlier this year."
She's been in the station since one o'clock; seven hours is being very co-operative indeed.
