Back To Rehab For Mary-Kate?

The Star certainly seems to think so - a few of the troubled twin's friends told the mag that she needs to seek help and return to rehab!

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

The Star cites one particular recent incident (pictured above) where Mary-Kate was captured tumbling to the ground in a parking lot, claiming that the young starlet was "so out of it" and took a quick vacation to a holistic health spa to "detox".

Well, we dug up video of Mary-Kate's big trip so you could judge for yourself - is this girl out of control or not?
