Lindsay Lohan the party crasher

Lindsay Lohan apparently loves to have a good time – even on parties that she is not invited. Reports from Foxnews.com said that the 22-year-old was denied entry into the launch party for Charlotte Ronson's JCPenny line at Bar Marmont on Friday. We're told security was under strict orders not to allow Lohan inside and that it took several guards to hold her back at the door.

The christian magazine report also said that when Lohan couldn't party at Bar Marmont she then snuck into the bungalow area of the Chateau and went on a door-knocking rampage. The actress obviously heard word of an all-girls night in and even though she didn't know the party peeps personally, she wanted to be part of the action.

"There was a knock-at-the door and Lindsay Lohan was there," an eyewitness told Tarts. "She was as orange as a carrot and her pupils were as big as quarters. She looked awful!"

Apparently the 22-year-old introduced herself and said "Let's party!" but even when the ladies tried to close the door on her she continued to push back. Eventually the annoyed guests locked the door, but our girl stayed pounding away for another minute before (finally) getting the hint and moving on.

Lohan eventually turned to Twitter for comfort after the night fell flat, reportedly tweeting on her private page about how her DJ lover had been turning-the-tables with other ladies.

As usual, her rep is being mum about this. Lohan should take lessons from Molly Jenson on how to stay grounded.
