Kirsten Dunst is still unable to control her alcohol addiction following a stint in rehab earlier this year, according to reports.

The Spiderman star checked into Cirque Lodge in Utah earlier this year, after friends and family became worried about her wild behaviour at the Sundance Film Festival.

However, just five weeks after leaving the Utah facility, the 26-year old was spotted in a New York bar looking worse for wear, drinking and dancing with friends.

A source Star magazine: "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."
