Mary-Kate Olsen (or Mary-Kate Trollsen, as I like to call her) may be headed back to rehab, but this time for addiction problems. MK has been partying like a rock star for the past few months culminating in a recent shocking public drunken collapse.

Star magazine reports that Mary-Kate’s binging started right after the death of “her lover Heath Ledger died tragically from a drug overdose.”  MK checked into a holistic health spa to detox after collapsing in a public parking lot last month, but it seems the natural way isn’t working for her. Friends say that MK’s behavior is putting a huge strain on her relationship with her sister Ashley as well. Once inseparable, the Olsen twins are rarely seen together.

“Mary-Kate seriously needs to get to rehab, but she doesn’t think she has a problem,” says a source. “She thinks she’s young, hip and entitled to live her life as she sees fit. But it’s affecting everything.”
