Just five weeks after her stint in rehab, actress Kirsten Dunst is reportedly losing her battle with an alcohol addiction.

The 26-year-old star of Marie Antoinette and Spider-man was admitted to Cirque Lodge, a high end rehab facility, after a heavy week of partying at Sundance Film Festival in Utah more than two months ago. The move came after an intervention with Dunst’s family and friends.

But while everything seemed to go according to plan, during a break from filming, in order to celebrate her birthday, Dunst was seen drinking and dancing in a local bar in New York City with several friends. One of which, according to IMDb, was The Strokes’ drummer Fabrizio Moretti (who dated Drew Barrymore for more than three years).

“She got worse as the night went on,” a source told Star magazine. “She started out pretty chill, but hours later she was dancing and jumping like a crazed animal. She indulged in any guy who would have her attention. It’s obvious that whatever happened in rehab didn’t stick.”
