Winehouse, who dyed her hair blond and ditched her signature black hair done up in a beehive hairdo, can be 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.
Her publicist, Tracey Miller, declined to comment Tuesday.
A statement issued by Universal Records, Winehouse's record label said, "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."
Winehouse -- with her erratic behavior -- has fed the tabloids a consistent diet of melodrama in recent months thanks to lackluster performances, reports of alleged drug use and her relationship with Fielder-Civil.
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 Grammy Awards including best new artist and album of the year for her acclaimed disc "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.
