+Hollywood actress Kirsten Dunst has become the latest star to reportedly check into rehab - joining the same Utah medical facility as Eva Mendes.

According to U.S. magazine Star, the 25-year-old was admitted to Cirque Lodge after a week of wild partying at last month's Sundance Film Festival.

The facility is also the same centre where Lindsay Lohan spent last summer for substance abuse problems.

A source tells Star, "She (Dunst) 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 not in a good place right now, but thankfully, she's getting the help she needs."

Dunst recently dismissed rumors she was on the verge of a breakdown after reports surfaced of her alleged "erratic" behaviour at Sundance, with sources claiming her "odd" antics left friends apologising to other partygoers. But representatives for the Spider-Man star denied the reports insisting, "Kirsten is fine."
