Despite the fight that Lindsay and Samantha had in London the other night, they were all smiles in Dubai today at the grand opening of Atlantis The Palm, posing with Samantha’s mom, socialite Ann Dexter-Jones. I’m sure this was a killer party — they know how to do it up right in Dubai, from everything I’ve heard. Exactly the place that a “recovering” drug and alcohol addict needs to be.

Also there: perennial party girls Mary-Kate Olsen and Mischa Barton, as well as Charlize Theron, Kylie Minogue, the jail-bound Wesley Snipes, and Michael Jordan — yes, that Michael Jordan.

We knew early on that the fight was over Calum Best, but now we have even more deets on their fight in London the other night.

We hear that things got pretty tense at London’s Boujis Wednesday night after DJ Samantha Ronson spied her lover Lindsay Lohan chilling with her former squeeze Calum Best.

According to eyewitnesses, Sam was leaning into her cocktails when she saw Lindsay on the dance floor with the former model. Calum is said to have been the one who came over to her and Lindsay was enjoying the attention — and the flirting.

Sam is said to have gotten so angry that the two gals had to be restrained to keep them from beating on each other.

Mark my words. This thing is going to implode, and it’s going to be nasty, and the odds are good that it’ll result in another DUI for Lindsay.

Okay, it’s not actually video of them fighting, but it’s video of them going into and out of the club, and then of Samantha storming out of the limousine and leaving Lindsay behind, with Beyonce’s “If I Was a Boy” blasting through the windows. Lindsay sits in the car and dramatically sulks for awhile before leaving herself.

The fight they had last night was supposedly over Calum Best, who showed up at the club they were at in London. Calum used to bone Lindsay, and Samantha is reportedly really jealous of any of Lindsay’s former lovers. Ugh. Been there, Linds. I feel ya.

Lindsay Lohan and Samantha Ronson made their first official ”We Are A Couple” red carpet appearance last night.  I mean, they’re always seen together stocking up on Doritos and Red Bull or appearing at clubs but this is different.  This is a statement people.  And I know that Lindsay said she’s sorta, kinda, maybe bisexual but really, is Samantha Ronson thatmuch of a stretch?  Ronson is every guy I dated in 1988.  When I see pictures of her, I am flooded with the smell of Oxy10 and Polo and, oddly enough, cherry Chapstick.  How can LL tolerate the GNR shirts another day?  I just know that if I decided to take chicks for a spin, I’d expect lip liner and push-ups…not zebra pattern high-tops.  I guess as long as our favorite celebulez is happy with her ear scratching DJ that’s all that is important.  And she does appear to be happier and healthier.

Just hours after these pictures were taken, PETA poured a bag of flour on Linds in protest of the fur she’s been wearing lately.  The relationship between flour and fur?  I have no idea.  Maybe they just wanted to take the edge off of that perma-tan.

UPDATE:  Some reports are coming in that the flour incident happened before these pictures were taken and that the two were de-floured with a vacuum.  Hard to believe.  Pictures of Lindsay getting floured here.

Okay, so, my friend Trish keeps talking about this book called Skinny Bitch, basically about how you have to be all vegan and shit to truly be healthy, and she’s like, “Listen, Beet, I don’t think you should read it unless you’re ready to be vegan. It’s the kind of thing you can’t unread.” And I went a few months without reading it, but then last night I gave in and bought it and I’m about halfway through, and I think I have to be vegan now. The poor animals! It’s SO AWFUL how they’re treated — I just can’t be part of anything that encourages that industry. I just think of anyone doing that to Leo or the kitties and it makes me so angry! And Californians seem to understand those horrors — they passed an animal-rights initiative on Tuesday, while revoking the rights of gay couples to marry.

Samantha Ronson sums it up nicely on her latest MySpace blog:

2 steps forward….. 2 steps back

i guess people care more about farm animals than they do their fellow man, that’s really sad to me.

yes, i am glad that the chickens will have more room and better conditions as they wait to die, but i just think it’s frightening that people show more compassion for tomorrow’s dinner than for the chef.

yup, miss piggy and chicken little may rest easy, but gay people in florida and california can no longer get married and gay couples in arkansas can’t adopt children. g-d forbid a loving family (regardless of sexual orientation) give a needy child a home! there aren’t children out there in dire need of love and shelter, no this country is thriving and no child is in need.

oh well, i guess one out of four ain’t bad!

You tell ‘em, Sam!

Lindsay Lohan has agreed to allow her deposition for Samantha Ronson’s malpractice and negligence lawsuit against her former lawyer (related to this) to be videotaped as long as her conditions are met:

Lohan’s lawyer asks that the video be used only in the current suit and never for future litigation, minus a judge’s order; that only the parties to the suit, their attorneys and expert witnesses can view the tape; that no one be present for the deposition other than the plaintiff and defendant, the lawyers, a cameraperson and a court reporter; that Lohan’s lawyers keep the original copy and others are only available to the other side’s attorneys; that no more than four transcripts are produced; and, that when the case is over, all copies be returned to Lohan’s camp and all transcripts destroyed.

Do average, everyday people get to submit their list of demands like this?  I know, I know.  She’s famous and I am sure the video would be leaked to the media…just makes me wonder what she has to say that could, in the words of Lindsay’s lawyer, cause such “unwarranted annoyance, embarrassment, oppression, undue burden, and expense.”
