Lindsay Banned From Charlotte Ronson's Party!?

Uh oh! Looks like there's drama in Rohanland yet again, and we're sure Lindsay is fuming about this one...

According to OK! Magazine, Lindsay was banned from entering Charlotte Ronson's "I Heart Ronson" clothing launch party at the Chateau Marmont last night! Sam was DJing at the event, and sources tell the mag that when Lindsay tried to get in, she was "held back at the door by five bouncers"!

The doormen were reportedly under strict instructions from the Ronson family "to look out for Lindsay and not to let her in under any circumstances." One insider added that the Ronsons had gone out of their way to insure Sam's lady love wouldn't be able to get inside. "Lindsay knew she was unwanted, but came anyway, to no avail," said a source.

So was Sam cool with all this? One eyewitness said, "She looked like she was in a great mood," and she continued to spin records even after the party ended at 11pm.

Would Sam REALLY do this to Lindsay? I mean, this is bordering on public humiliation!
