Utah- [Star Magazine] Kirsten Dunst has checked herself into Cirque Lodge in Utah, Star has learned exclusively.

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.

Fox News adds: A rep for the facility denied to E! News Friday that the actress is there.

“Nope, not true,” said Gary Fisher, the lodge’s director of operations.

A source at Cirque Lodge said the actress checked into the clinic this week after a week of hard partying at the Sundance Film Festival, “Entertainment Tonight” and Star magazine reported Thursday.

Dunst reportedly burst into tears when she signed herself in.

Cirque Lodge is the same facility where actresses Lindsay Lohan, Eva Mendes and Mary-Kate Olsen have sought treatment for various problems.

FOXNews.com’s request for a comment from Dunst’s publicist was not immediately returned.
