Scotland Yard started an investigation Wednesday into a video that allegedly shows troubled British singer Amy Winehouse smoking crack.

The British tabloid, The Sun, released grainy footage showing Grammy-nominated Winehouse, 24, inhaling fumes from a pipe. The video was reportedly shot hours before she attended a court hearing for her jailed husband.

Police will look at the video before deciding whether any charges should be brought against Winehouse, a Metropolitan Police spokesman said while speaking on condition of anonymity in line with force policy. The Sun gave the police the video, he said.

Winehouse spokesman Shane O'Neill said he was unable to comment on the investigation.

In the video, Winehouse lights a pipe in front of a photo that appears to have been taken on the day of her wedding to Blake Fielder-Civil.

Winehouse's father, Mitch Winehouse, said in an interview with The Sun that he was devastated by the images and hoped it would prompt his daughter to turn her life around.

"Your video of Amy taking drugs may well be the best thing that has ever happened to her," the newspaper quoted him as saying.

Universal Records, Winehouse's record label, said it would do what it could to help her.

"We are deeply disappointed and upset by these latest revelations and are doing everything we can to offer Amy our full support in dealing with her problems," it said in a statement Tuesday.

The singer's public demise amid allegations of drug use and lackluster musical performances have provided fodder for Britain's notoriously scandal-hungry newspapers.

Last month, the troubled singer, whose songs include "Rehab" and "You Know I'm No Good," was photographed walking outside her London home wearing a bra and jeans, with no shoes, looking upset.

Winehouse attracted yet more attention in court Friday when she blew Fielder-Civil kisses and shouted out, "I love you, handsome, gorgeous one," as he was led away after facing charges of assault and conspiracy.

Fielder-Civil, 25, is accused of attacking a pub landlord and then later conspiring with him to withdraw as a witness at the trial. Fielder-Civil pleaded innocent to the charge of assault, and is expected to plead to a charge of perverting the course of justice next month.

Winehouse is nominated for six Grammys including best new artist and album of the year for "Back to Black," plus record and song of the year for the brassy hit "Rehab." The awards will be presented Feb. 10 in Los Angeles.
