According to Star rag (a source one must always take with a grain of salt) Kirsten Dunst has said "Bring it On" to the Cirque Lodge rehab facility in Utah, after partying a little too much at Sundance.
"She desperately needed help," a source tells the mag. "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."
UPDATE: A source close to Kirsten confirmed to People.com that the actress is in rehab. "She's not doing well," the source says. "People were pushing her to go in there but there was no intervention... She has been partying hard for a while and I'm sure the Heath Ledger thing put people over the edge."
