LONDON: Actress Kirsten Dunst is drinking again after a year-and-a-half-long battle to stay sober, according to a U.S. report.

The Spider-Man star was thought to be alcohol-free since a spell in rehab last year (Feb08) - but a sighting of Dunst drinking in a Los Angeles bar on 18 August (09) have sparked fears for her health, reports the National Enquirer.

A source tells the tabloid, "She told (a companion) to order her double vodka on the rocks... (he) held her by the arm to keep her stable. Even though she was wasted, she looked like she was trying to hide her drink in her jacket as she walked toward a couch. But minutes after she sat down, Kirsten gulped her drink."

A spokesperson for the 27-year-old actress had not responded to requests for comment as WENN went to press.
