Actress Kirsten Dunst has prompted speculation she is losing her battle with alcohol addiction just five weeks after leaving rehab, according to reports.

The 26-year-old star was reportedly admitted to Cirque Lodge earlier this year (Feb08) after a wild week of partying at the Sundance Film Festival in Utah, prompting family and friends to seek intervention.

But, during a break from filming while on location in New York to celebrate her birthday earlier this month (02May08), she was allegedly seen drinking and dancing with pals - including The Strokes' Fabrizio Moretti - at a local bar.

A source tells U.S. magazine Star, "She got worse as the night went on. She started out pretty chilled, but hours later she was dancing and jumping like a crazed animal.

"She indulged in any guy who would have her attention. She also went up to several guys and started flirting with them hard-core. She was just completely out of it. It was obvious that whatever happened in rehab didn't stick." (JMA/TS/MT)
