Amy Winehouse was arrested today and is being questioned by police over alleged drug offences.
The troubled singer is being interviewed at an east London police station, her spokesman said.
Scotland Yard said a 24-year-old woman attended a police station by appointment and was arrested in connection with the possession of drugs.
Scotland Yard said the arrest was in connection with a video of the star passed to them in January.
On January 22, a newspaper published pictures apparently showing the 'Rehab' singer smoking crack cocaine.
Footage obtained by The Sun appeared to show her inhaling fumes from a crack pipe after a 19-minute drugs binge.
The star was also shown apparently snorting ecstasy and cocaine and admitting downing six Valium.
A spokesman for the singer said: “She is being questioned in a police station. We will be releasing a statement later.”
A spokesman for Scotland Yard said: “Around 1pm today a 24-year-old women from the Camden area attended a London police station by arrangement and was arrested in connection with the alleged possession of a controlled drug.
“She remains in custody. This is in connection with an investigation connected to footage passed to the Metropolitan Police on January 22.”
