Word On The Street ...

We're hearing that Lindsay was partying at Koi restauranteur Nick Hawk's party house (where he hosts late-night after-parties) last night and that a fight broke out there -- between who, we're not sure. We hear that Lindsay left Hawk's Mt. Olympus (Hollywood Hills) house in a huff and her bodyguard Jaz was left to clean up the mess inside as Lindsay waited in the car.

Then at 5 am, DJ Samantha Ronson left Lindsay's place, walking up Doheny to Sunset and Lindsay went after her. Lindsay caught up with Samantha as she was in the median of the four-lane Sunset Blvd. and she tried to talk to Sam -- they were screaming, obviously arguing, and Lindsay was heard by our photographer saying, "You f*cking lesbian bitch."

Samantha ended up getting into the car with Lindsay and her male friend and they sped off down Sunset (pushing the pedal to the floor in Lindsay's 600 horsepower Mercedes SL 65). Lindsay was going west on Sunset and lost control of the car, veering off on to Foothill, jumping the curb, and crashing into a hedge.

Lindsay must have then called her bodyguard Jaz to tell him to come pick her up. He arrived in his Mercedes G-Wagon, switched cars to drive Lindsay's wrecked convertible home, while one of the passengers from Lindsay's car chauffeured that trio -- they probably went back to Lindsay's and then to the hospital, but that's where our timeline ends.
