While Lindsay Lohan keeps whining to the press that she and Samantha Ronson are not broken up, everything’s fine and she’s totally sober, her actions certainly don’t reflect any of those statements. On Friday night, Lohan’s girlfriend Sam Ronson was spinning at a party for her sister Charlotte at Bar Marmont. Apparently, the door men at the gig were given strict instructions not to let a certain redheaded actress into the party – but that didn’t stop Lohan from trying to get in anyway. TMZ has photos of a dejected looking Lindsay outside the club.

It looks like Lindsay Lohan and Sam Ronson’s latest break-up might just be the real thing.

There was major drama in L.A. late Friday night at Bar Marmont, where Sam was DJ-ing at a party for her fashion designer sister, Charlotte Ronson’s I Heart Ronson clothing line for JCPenney. It all started when Lindsay tried to get into the party, only to be held back at the door by five bouncers!

Sources tell OK! the doormen were apparently under strict instructions from the Ronson family to look out for Lindsay and not to let her in under any circumstances.

The party officially ended at 11pm on Friday, but an hour later, Sam was still spinning records inside, while Charlotte, their brother Mark — whose band played an hour-long set at the event — and their mom, Ann Dexter Jones partied on.

Before Lindsay’s arrival at the event, an insider told OK! that the Ronsons had gone out of their way to insure she wouldn’t be able to get inside. “Unless Lindsay rams a truck through the red carpet or skydives in, she won’t be here,” revealed the source.

But just as expected, Linds still showed up, only to be “restrained from coming in by five security guards,” according to an onlooker.

“Lindsay knew she was unwanted, but came anyway, to no avail,” said another source.

Judging by her behavior inside the event, Sam was completely fine being in a No-Lohan zone. “She looked like she was in a great mood,” one witness tells OK!.

While LiLo couldn’t get beyond the guardians at the gate, other celebs, including Nicole Richie, Molly Sims, Sting and Jewel, had no problem getting into the event. Even Paris Hilton was welcome. The celebutante arrived around 10:15pm on the arm of her boy-toy Doug Reinhardt. “She really seemed to be glowing!” one partygoer tells OK!.

It was a second night in row that Lindsay had displayed some odd and seemingly unwelcome behavior.

On April 2, also in L.A., she suddenly popped up onstage in the middle of pal Lily Allen’s show — only to be all but ignored by the British pop star.

It’s pretty clear what’s going on here: it looks like Sam has finally had enough. I wonder how long it will take for Lindsay to wise up and get back into treatment? What will it take this time – another DUI? And what happened to Michael Lohan’s big plan to have one of the Baldwin brothers stage an intervention for Lindsay? Sounds like she could use some help right about now.
