Proving that old habits die hard, Kirsten Dunst is reportedly back on the booze.

After spending the past 18-months trying to stay sober following a stint in rehab last year, the 27-year-old actress was spotted drinking in a Los Angeles bar on August 18.

“She told [a companion] to order her a double vodka on the rocks… he held her by the arm to keep her stable,” a souce has been quoted as saying. “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.”

Last year, Miss Dunst played coy about the reason behind her stay at Utah’s Cirque Lodge rehabilitation center, saying : “I wasn’t taking care of myself emotionally. I wasn’t expressing my anger. I was making nice all the time.”
