'Mary-Kate Olsen Needs Rehab For Wild Drinking Binges'

Mary-Kate Olsen is in dire need of another trip to rehab, according to a US publication.

The pint-sized star – who has previously sought help for an eating disorder and cocaine addiction – has reportedly been indulging in "wild drinking binges" as she struggles to cope with the death from an accidental drugs overdose of party pal and rumoured "lover" Heath Ledger in January.

"Mary-Kate seriously needs to get to rehab, but she doesn't think she has a problem.

"She thinks she's young, hip and entitled to live her life as she sees fit. But it's affecting everything," a source tells Star mag.

The publication also claims that the minted troll failed to curb her hard-partying ways with a trip to a holistic spa recently.

Poptarts reported this week that Mary-Kate celebrated the Fourth of July with model Jessica Stam in the Hamptons, where she happily chowed down on a barbecue and refused offers of alcohol.

Their source said of the star, “I’ve never seen her [Mary-Kate] in such good spirits, and she didn’t look anything like her old emaciated self."
