The “Labor Pains” actress and her lesbian lover were spotted leaving their New York City hotel along with some luggage, as Sam gave her sister Charlotte a hug before heading off in a chauffeured car.

In related news, despite LiLo’s repeated attempts to assure everyone that she and Ronson are still going strong, their night of clubbing on Thursday sure looked to the contrary.

The night started off just fine, with Samantha manning the DJ booth at Tenjune for the MySpace Holiday Party.  A partygoer reported, “They were in such good spirits,” an eyewitness says. “Lindsay kept hopping in and out of the deejay booth, giving Sam plenty of attention.”

But later on, at the 2008 NASCAR Sprint party, held at Marquee, Ronson’s lack of attention for Lohan caused Lindsay to freak out a bit.  An eyewitness revealed, “Sam was roaming the party and chatting with people, and Lindsay just seemed to melt down literally.”

The “Mean Girls” babe and her deejay love were spotted looking pretty gloomy as they left London hot spot Boujis, with LiLo waiting in the limousine for 10 minutes before Sam came out.

Onlookers seemed to think the falling out was over Lohan’s ex-boyfriend Calum Best’s arrival at the club, which marked the second time in a week he’s turned up at the same club as Lindsay and Sam.

Once back at their hotel, Ronson stormed out of the limousine, leaving Lindsay to sit and sulk by herself before finally going in.  An inside source told press, “Samantha gets jealous of her former male lovers, and Lindsay didn’t want to upset her.”

The “Mean Girls” hottie and her celebrity deejay girlfriend began the evening with a romantic dinner date at Cipriani restaurant before heading back to their hotel to change clothes.

Re-emerging in full party gear, LiLo and Sam headed out to Dolce nightclub, where Lindsay subsisted on soft drinks throughout the evening.

Finally around 2:30am, the happy twosome made their way over to the Notting Hill Arts Club where they partied until 4:30am, meeting up with UK pop star Lily Allen along the way.

The “Mean Girls” hottie looked a bit rushed as she posed for the paparazzi, sporting a black minidress with blue suede heeled ankle boots, while her deejay girlfriend opted for a white t-shirt with a black vest and black trousers
After giving a few brief interviews, LiLo and Sam sauntered inside the club where Ronson proceeded to the deejay booth for a set.

The “Mean Girls” actress and her deejay sweetie looked to be having a marvelous time as they meandered around the Top of the Rock, located inside Rockefeller Center, with LiLo socializing while Sam kept the tunes spinning.
And she just may get her wish.  When asked about teaming up with Lohan, Madge recently responded, “Yeah, sure.  Why not?”

Toting a bottled water in-hand, the “Georgia Rule” starlet sported black Rayban sunglasses to go with her black leggings and boots, managing to give a passing smile to a photographer on the scene.

Meanwhile, recent rumors tell that LiLo and girlfriend Samantha Ronson’s relationship is hitting troubled waters, despite the fact that the twosome attended Madonna’s Madison Square Garden concert a few nights back.

According to a report from the Daily Mail, Lohan and Ronson “are said to be drifting apart and bickering on a daily basis,” with friends saying that DJ Samantha feels “smothered by Lindsay’s constant attention and is anxious to step away from the media spotlight.”

The “Labor Pains” actress looked a bit retro-80s in a long black t-shirt with a navy vest and a black leather jacket with black leggings and black leather ankle boots, while Sam rocked a white Pink Floyd t-shirt with a black leather jacket, black jeans, and white sneakers.

According to a source, she’s going to make it as authentic as possible.  “The costume will include the glasses, the perky red suit and ample cleavage.” Even better, Ronson is reportedly going as Sarah’s husband Todd Palin.
