It seems that Kirsten Dunst has been having substance abuse problems as she has checked into the same rehab where Eva Mendes is staying:

Spider-Man’s Mary Jane made the decision to follow in the footsteps of Cirque patients such as Lindsay Lohan and Richie Sambora — after a week of wild parties at last month’s Sundance Film Festival. Fellow actress Eva Mendes is also in the mountaintop facility right now. Mary-Kate Olsen was treated at Cirque for food issues.

“She desperately needed help,” a source in Utah tells Star. “She seemed to be intoxicated when she checked in because she was acting really erratic. She was extremely emotional, constantly breaking down in tears.

“She not in a good place right now, but thankfully, she’s getting the help she needs.”

This isn’t the first we’ve heard about Kirsten’s drunkenness, she gave this revealing interview in 2005.

The stunning actress is alleged to have arrived on the red-carpet of the New York premiere looking “dishevelled” before drinking herself into an aggressive stupour at the exclusive post screening bash. According to one fellow reveller, who was quoted by America’s New York Post newspaper, Dunst was “drinking a lot and got very loud and obnoxious. She was very pushy.”

She told American talk show host Jay Leno: “I stock up on Veuve Cliquot champagne. I buy it from Costco – cheap there I have lots of alcohol and no food in my fridge”. When asked by Leno whether she was worried about her drinking habits, the screen beauty added: “Well, maybe in a few months you will see me in a rehab clinic.”

I’m pretty sure her ‘maybe in a few months you will see me in a rehab clinic’ comment was meant to be a joke, but maybe she sort of knew she was falling off the wagon. Then again, isn’t drinking something everyone does in their late teens and early twenties? The legal drinking age in America is 21, but in other countries it is 18. Maybe this is why is has take her so long to admit she might have a problem, because everyone else is drinking to excess at parties. Which I think your liver and brain can cope with for a short period of time, although it always seems to feel very badly the next morning.

The again, the report is a Star Magazine exclusive, and they’ve been known to be wrong a few times. 25 year-old Kirsten only has one movie coming out this year, How To Lose Friends and Alienate People, and another coming out in early 2009.

Note by Celebitchy: There were rumors that Kirsten was “in a bad place” at Sundance, but her rep denied that there was anything wrong. She was also seen publicly making out with Josh Hartnett there.
