The ongoing quarrels between “are they or aren’t they” girlfriends Lindsay Lohan and Samantha Ronson are reaching epic proportion. Sam and Lindsay seem to be arguing everywhere they go – on planes, trains, automobiles and even walking down the street together. The latest public spat happened at a nightclub in London, where Ronson was the guest DJ. Apparently, Sam was getting a lot of attention from the ladies, and Lindsay didn’t like it.

Party-mad Lindsay Lohan was keen to show her friends some real fun in London – but had a far from capital time.

The night out was full of jealous tantrums and lovers tiffs, and ended in an undignified scuffle at 4am.

The Hollywood star and her pals crowded into celebrity haunt Chinawhite on Wednesday, where LiLo’s DJ lover Sam Ronson was on the decks for the F*** Rehab night.

But Lindsay – who ordered vodka disguised in a fruit jug – got her knickers in a knot when girl fans began hurling their panties into the DJ booth.

She was also incensed to see them handing Sam drinks receipts with their numbers on the back.

LiLo, 22, ordered her flunkies to move the flirts away. Then left everyone in no doubt Sam was taken.Our spy says: “She crawled on all fours under the bar and nestled up to Sam on the decks, hugging her as if to say she was her girl.”

But later the tables were turned and it was Sam’s turn for a strop.

We hear: “Lindsay disappeared halfway through Sam’s set. When Sam later found her in their V-VIP booth, this girl was stroking Lindsay’s arm and giggling with her.

“Sam shot daggers at the girl, who left immediately.”

It’s a good job jealous Sam, 31, failed to spot that Lindsay’s old flame Calum Best was also in the club – sat as far away from them as possible. Phew! Still, Lindsay got back in Sam’s good books.

Our spy adds: “They went in for a full-on tongue sandwich, their hands all over each other. Nobody knew where to look.”

Sam then performed a steamy lapdance for Linds as DJ Sam Young played Katy Perry’s I Kissed A Girl for them.

Subtle, or what?

Then a scuffle broke out at 4am as Lindsay and Sam were leaving. We hear: “There was a lot of pushing and shoving as one of her guests got left behind. Lindsay was screaming: ‘I’m OK. I’m a big girl, I can take care of myself’ as minders shielded her.

“She was overheard blubbering: ‘I just wanted to make sure everyone had a good time. I didn’t want anyone to get hurt. I’m so, so sorry.’”

Somehow I can’t see Samantha Ronson performing a “steamy lapdance.” Well, I can picture it, and then my breakfast starts to come back up.

At first I didn’t believe the stories of these two and their non-stop, immature bickering. But there have been so many of these incidents lately, you can’t help but think they’re at least partially true. If so, I don’t see them lasting much longer- especially if Lindsay is drinking again. Based on her past history, Lindsay has quite the temper when she’s drunk. It can’t be much of a picnic for Samantha to be around that.
