Mary-Kate Olsen, who previously spent some time in rehab for an eating disorder, might be headed back to rehab, according to Star magazine.

According to the magazine, the pint-sized star has been on a long party binge since her alleged "lover" Heath Ledger passed away in January. According to Star's sources, Olsen has been binge drinking so much so that she collapsed in a public parking lot and needed to visit a holistic health spa in order to detox.

"Mary-Kate seriously needs to get to rehab, but she doesn't think she has a problem," a source close to the actress told Star. "She thinks she's young, hip and entitled to live her life as she sees fit. But it's affecting everything."
