Kirsten Dunst checks into rehab?

Kirsten Dunst has reportedly checked into rehab after weeks of hard partying.

After her “erratic behaviour” at the Sundance Film Festival drew comment from various quarters, Kirsten is said to have checked into the Cirque Lodge facility in Utah last week.

An inside source told Star magazine: “She desperately needed help. 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 is not in a good place right now, but thankfully, she’s getting the help she needs.”

Kirsten isn’t the only celebrity currently in treatment at the clinic made famous by Lindsay Lohan’s two month stay last year: Eva Mendes checked in for treatment last week for help with “some personal issues”.
