Samantha’s twin sister, Charlotte Ronson, reportedly barred Lindsay from her “I Heart Ronson” fashion show on Friday night, leaving the starlet outside Bar Marmont, restrained by five security guards.

OK! says that when Lindsay tried to enter, she was reportedly “held back at the door by five bouncers,” because they were apparently under strict instructions to “look out for Lindsay” and “not to let her in under any circumstances.”

The magazine’s source says that before the show, the Ronson family had gone out of their way to keep the actress out: “Unless Lindsay rams a truck through the red carpet or skydives in, she won’t be here.”
And a source at the party confirms to E! that the Ronsons had asked Lohan not to attend.

As Sam DJ’d at the event, Lindsay retreated to her room at the Chateau Marmont. Lindsay then did the next logical thing: she Twittered about her failed relationship with Sam, accusing Sam of cheating, and adding that Charlotte needed lose “a stone or 10.”

Sam kept a low-profile for the rest of the weekend. On Saturday, photographers snapped a locksmith changing the locks on the homshee used to share with Lindsay. Meanwhile, Lindsay stayed at the Chateau Marmont with her mother and sister.

In the wake of rampant reports of friction between the couple, TMZ published a story on Monday evening claiming that Lindsay Lohan and Samantha Ronson ended their relationship. Shortly after, Lindsay spoke out on her Myspace blog, denying she and Sam called it quits.

RUMORS

little piece of TRUE information:

we did NOT break up!

access hollywood, extra, et, every tabloid, page six… AND every GOSSIP website. Get your stories straight please. It’s really annoying to have all of your friends emailing you saying, i saw, i read, etc… NOT TRUE

xoxox Lindsay

They may not have broken up over the weekend, but you know that shit is coming. And, no, I don’t think it’ll be because of the fighting. It’s gonna be because of dick. Lindsay’s gone over year without it. You know she’s dying on the inside. Sincerely – and I swear to god I’m not exaggerating here – when they finally break up, I wouldn’t be surprised if Lindsay fucks 10 guys that night.

Everything is right with the world again. Paris Hilton is single and Lindsay Lohan has been getting trashed every night in London for the past week. Look at those bags under her eyes. Anyway, Lohan and Ronson got into a fight in London last night over a big dick named Calum Best. Lohan used to rub her worn-out kitty all over Calum’s Gouda peen and the two met up again at a club. A source said Lohan and Calum danced together which made Samantha Ronson one angry lezzie. Lohan and Samantha apparently started fighting which ended in both of them leaving the club.

They got into the car together, but when they arrived back at their hotel, Samantha stormed off in a cloud of saw dust. You know, because lezzies like wood working and stuff. Yeah, the joke doesn’t really work if I have to explain it in detail. Just give me an endearing look and continue eating your panini.

Lohan stayed behind in the car for around 10-minutes. One source said, “It was quite clear something was up. Lindsay had tears in her eyes as she left.”

Okay, you know shit is bad when you’re fighting about Calum Best! The douche isn’t even hot when you look at him upside down while jacking it. Almost everyone is hot when your head and genitals are fighting for blood flow. Don’t look at me that way!
