Kirsten Dunst checks into rehab

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."

Kirsten, 25, has long had a reputation for partying, with bloggers giving her the unfortunate nickname of Kirsten Drunkst.
