Source: Lindsay Lohan is an "Obituary Waiting to Happen"

Lindsay Lohan once got into a car accident because she was high on cocaine.

She also went a long time without wearing underwear, flashing anyone that looked in her direction.

Still, according to a new report, the troubled actress has not hit rock bottom... until now!

During her recent trip to Paris for a fashion show, Star magazine claims Lohan collapsed while partying. The tabloid cites her reliance on vodka, cocaine and prescription pills as a dangerous habit, and quotes an anonymous friend as saying:

“She’s a wreck, a mess, a disaster. She an obituary waiting to happen.”

Lohan has entered rehab three times, and been arrested twice for DUI. Still, she can't stop drinking and going out, sources say.

An insider says Lindsay "was crushed" by harsh reviews for her Emanuel Ungaro clothing line. Afterward, she attended a party hosted by photographer Mario Testino and, as a source relays:

“Her eyes were red and puffy, and at one point she started shouting and tearing up. Her friends had to get her out of there before things got any worse.”

Added a supposed friend, who cited Lindsay's faltering career and the end of her relationship with Samantha Ronson: “She’s definitely hit rock bottom. The next level is six feet under.”

Note to Dina Lohan: we'll leave your daughter alone, if you agree to stop referring to her as a "genius." Start acting like a mother, acknowledge her issues and get her help. Deal?
