Boston-bound Sam Ronson slams Lindsay Lohan

Remember the Miami-based gig DJ Samantha Ronson and her crimson-haired gal pal Lindsay Lohan were heading to on Dec. 29 in preparation for their big New Year's Eve bash sponsored by SoBe Lifewater at Miami's Mansion?

Well, all hell broke loose at the party, writes gossip wrangler Perez Hilton.

Ronson. slotted to spin on Wednesday, Jan. 21 for the Winter White Party at The Estate in Boston, fought with a "really unstable" Lohan who allegedly flipped out in front of partygoers. The spat reportedly spilled out into an alley behind the club where one source says Lohan screams, "When I storm off, you are supposed to follow me."

At their Miami hotel, sources claim, "They were punching each other-- it was bad. And they were doing this in front of all of us. It was scary."

And, at one point, Lohan allegedly drops to her knees and cries, "Why are you doing this to me?" Ronson supposedly responds, "I don't know you."

No word if Lohan will make the trek to Boston on Jan. 21 to stand by her girlfriend. However, if their NYE spat is a precursor of things to come, let's hope the fallen child star drama stays home.

UPDATE: Lohan responds to the break-up "rumors" surrounding Ronson on her MySpace blog here. "Get your stories straight please," she shoots back. "It's really annoying to have all of your friends e-mailing you saying, i saw, i read, etc... NOT TRUE." And, Lohan is now scheduled to host the event on Wednesday, Jan. 21.
