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 in London on Friday for her husband Blake Fielder-Civil who is fighting charges related to a pub brawl.

In the video, Winehouse is seen walking around. She sits down and, before lighting the pipe, can be heard saying that she's "had about six Valium." On the wall behind her is a photo of Winehouse and Fielder-Civil.

Police will look at the video before deciding whether any charges should be brought against the singer, a Metropolitan Police spokesman said. The Sun gave the police the video, he said.

Winehouse spokesman Shane O'Neill declined to comment on the investigation.

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.

"Of course it kills me to see my daughter on the front page of your newspaper like that," he told the Sun. "It's nothing short of devastating - thinking she wants to destroy herself. She'll be heartbroken about it all.

"But for all the hurt and pain, it may finally be the thing to focus her mind and convince her to get the help she needs to quit for good."

Winehouse, one of Britain's top-selling artists, has won critical and commercial success with her hit album "Back to Black," and was nominated for six Grammys in December.
