LONDON (AP) -- Amy Winehouse will not face charges over video footage that allegedly shows her taking drugs, her spokesman said Wednesday.

Police questioned the Grammy-winning soul diva for nine hours last week over a January video that appears to show her smoking a pipe usually used for crack cocaine during a party at her north London home. Police began an investigation after photos from the footage were published in The Sun newspaper.

Spokesman Chris Goodman said police had finished their investigation and confirmed no charges would be brought against the 24-year-old singer.

"Amy is pleased to be able to move on and concentrate on music and particularly looks forward to seeing her fans again at eagerly awaited festival performances this summer," he said in a statement.

London police confirmed that no further action was being taken against a 24-year-old north London woman arrested last week on suspicion of possessing illegal drugs. British police do not release the names of suspects who have not been charged.

The singer, best known for her breakthrough hit "Rehab," has seen her rapid rise to fame overshadowed by media attention on her turbulent private life studded with wild nights out and run-ins with the law.

Last month she was cautioned by police for assault after she slapped a man during a night out. That means no charges were filed, but the incident was placed on her record.
