Pals say that Lindsay made a series of abusive phone calls to GEORGE BESTís lothario son after a porn-style photo, said to be of the two of them, was posted on the Internet.

The blurry clip is thought to have been filmed on Calumís phone when they were an item last year and then forwarded on to one of his friends.

A source, who overheard the rant, said Lindsay was screaming: ìI can't believe you would ever f***ing do this to me, I should have listened to everyone.

ìI should never have f***ing trusted you."

Lindsay screeched down the blower for so long that she had to leave another voicemail to finish her abusive tirade.

The Mean Girl continued: "It's everywhere now, all over the net, everyone's seen it, how f***ing could you?"

God, Lindsay, you have such a big mouth. (And, no, that's not a comment about the size of Calum's member.) Had you just zipped it we would have went on believing that pic was just some random no-name blonde. Or maybe Dina.

UPDATE: It's not Lindsay. But you're still going to look anyway, aren't you, you perv.

Alcoholics Anonymous member Lindsay Lohan has lined up Svedka vodka to sponsor her 21st birthday blowout in Las Vegas, a rep for the brand confirmed to us yesterday.

It's part of a deal that could net the star up to seven figures for the July 2-3 celebration. That's even before the Wonderland rehab center she attended gives her a refund.

Other partners include Pure nightclub, Caesars Palace (which is providing a "specially designed" suite) and the Social House restaurant at Treasure Island.

In the pay-to-play world of celebrity events, Vegas nightclubs alone have been known to offer up to $400,000 to land a top name.

Lindsay's mother, Dina, has confirmed she is involved with AA. So, in view of the circumstances, is having a vodka maker sponsor the first birthday of legal drinking age a great idea?

Her rep said, "I am unaware of who is sponsoring Lindsay's birthday, as I am not the one planning it."

But Lohan's lawyer Mike Heller confirmed the vodka deal. "This should be one of the best parties ever," he told Us Weekly.

We're sure the vodka sponsor is just part of Lindsay's theme: Russian winter. There will be vodka in every glass, fur hats on every head, and freshly fallen snow on every flat surface.

And while we're on the subject of Lindsay, girl does not like being cheated on. MSNBC reports:

Lindsay Lohan threw such a hissy fit at a hotel where her boyfriend stayed with another woman that the ìMean Girlsî star was reportedly asked to leave the hotel.

Calum Best checked into Manhattanís trendy Soho Grand with a pretty young woman who was not Lohan, and the actress shortly checked in with another guy ó some believe to make Best jealous. Lohan tried to telephone Calum, but didnít get in touch with him, so she went out partying until 1:30 a.m., reports Star, then returned to the hotel and collapsed in the lobby.

ìShe was writhing on the floor and everyone could see that she wasnít wearing any panties,î an insider told the tab. Lohanís date and bodyguard seemed so appalled by the scene that they didnít do a thing to help her, a staffer told Star, and so the hotelís night manager carried Lohan to her room.

The drama didnít stop there. Lohan repeatedly telephoned Bestís room, and at one point, went to his door and banged on it. He came to the door and opened it a bit, she peeked inside and saw the woman there. ìShe went cuckoo,î a source told the tab. ìShe yelled at him, slammed the door and banged on it some more.î

Lohan was reportedly escorted back to her room, but after various other escapades, at 5:30 a.m. she was asked to leave the hotel ó and checked out at 6:30 a.m.

So the hotel was willing to put up with a pantyless floor show in the lobby, carrying Lohan to her room, and screaming and door slamming in the hallway without throwing her out, so what were these "various other escapades" that finally got her kicked out? Did she personally show her vagina to all the hotel's guests? Start a crystal meth lab in her suite's bathroom? Exactly how far is too far?

According to The People, Calum [Best] told friends about Lindsay during a night out the Stereo nightclub in New York this week and a source told the newspaper: ìHe told me Lindsayís really insatiable when it comes to sex. [He said] ísheís dynamite between the sheetsÖ No girl Iíve ever slept with comes closeí.î

The source went on to say: ìCalum was knocked out by her body. He said sheís got one of the best heís ever seen with all the curves in the right places. He joked Lindsay loved being on top during sex and controlling the pace but sometimes he felt he needed ear muffs because she screamed so much during sex.

ìCalum explained that because Lindsay was so fit he would often find it hard to keep up with her demands. Lindsay likes her sex rough and passionate and Calum says he has the bruises and bumps to prove it.î

ìHe joked their hotel room would often look like a whirlwind had run through it with sheets torn away from the mattress by the force of their bodies rolling across the bed.î

For the rest of the day all we'll think about is Calum Best, fuzzy pink earmuffs shielding the noise, lying on his back with the look of a frightened animal being attacked by a wild wildebeest on his face, just hoping that the coke will wear off and Lindsay will tire before sunrise so he can make a turkey sandwich, watch some VH1 Classic, and fall asleep.

The NY Daily News reports:

The opening of The Cove resort in the Bahamas last weekend was so chockablock with celebrities you had to watch out where you stepped. Strolling along the jungle paths that meander past streams and waterfalls, Lindsay Lohan and new boyfriend Calum Best suddenly felt an urge to make out. A startled passerby came upon the young lovers rolling around on the ground. "Don't mind us," Best told the stranger. "We're tourists."

The tourist excuse does not work for public copulation. It works if you're apologizing for getting in people's way when you're taking pictures. Or for wearing matching T-shirts with your family. Or for complaining that all there is to eat is gross local cuisine, and where are all the Ruby Tuesdays.

Lindsay Lohan locked lips with British scene-maker Calum Best at Wednesday's Nylon Magazine party – despite the frowns of some pals. "This isn't a serious relationship," one friend tells us. "He's a piece of shit. He's a wanna-be celebrity. Lindsay trusts people until they hurt her." Whatever their future, Lohan was in fine form at the Tenjune bash. "She was lifting up her skirt, and sending people over to [her friend, deejay] Samantha Ronson when she didn't like what she was playing," said a spy.

Man. Not only does Samantha have to suffer through her sexy friend only deigning to hook up with her when no available man-pork presents itself, she must suffer the humiliation, as a professional DJ, of Lindsay sending her minions over to critique her beat-matching and demand that she play more Fall Out Boy. Rumor has it that Lindsay also likes to hang around operating rooms, murmuring, "could you make the incision over there instead? I dunno, it's just prettier."

SNORTED 20 lines of cocaine in ONE night alone

STRIPPED down to a thong before inhaling the drug off a coffee table

BRAGGED of wild sex sessions with a host of celebrities including singer James Blunt and model Calum Best.

STRIPPED down to a thong before inhaling the drug off a coffee table

BRAGGED: "I'm going to New York tomorrow to fuck Jude Law."

The mag's source says:

"That night I saw her do more than 20 big lines of cocaine. She was still up doing drugs at 11am even though she had started about 8pm the night before.

"She wasn't even trying to hide it and was blatantly doing it off table tops, keys, books and in the wardrobe, where she was hunched over with her legs crossed almost bent in half doing it off some magazine on the floor.

"I remember looking at her and thinking how pathetic she looked and how out of control she had become.

"When she is on coke, which is most of the time, all the attention has to be on her.

"I have lost count of the number of times I have watched as she stripped naked in front of everyone.

"Then she loves to check herself out in the mirror as she parades around with her boobs hanging out.

"One night we had gone back to her place and, as always, as soon as she walked through the door she stripped down to her thong, bent down and snorted cocaine off her coffee table and then off her toilet seat."

Oh, and about all those dudes she's f'ed:

"She has told me that she has slept with James Blunt, Jude Law, Calum Best, Joaquin Phoenix, Benicio Del Toro, Jared Leto and James Franco," admitted the friend.

"She loves Brits and has told me she has slept with the singer James Blunt a few times over the past month.

"The last time was on April 15 after another house party. I think they went back to a hotel together afterwards. She is very protective over him and when she heard I had met him she sent me a text saying, ëStay away from him Bitch, he is mine.'

"Lindsay told me she has messed around with Leonardo DiCaprio a while ago too but claimed that she didn't sleep with him.

"She also flew to New York about two months ago to go to bed with Jude Law.

"Last November she slept with Calum Best. She didn't tell me if he was any good but she is usually too wasted to know what is going on anyway."

Hey, we're not done yet:

"Going to rehab was all for publicity. She wanted people to see her seeking help but it hasn't got her off the drugs at all.

"In an average night Lindsay will do two and half grams of coke on her own.

"She doesn't buy itóshe is given it by friends and acquaintances, and it turns her into an angry monster. I have watched many a time Lindsay treating her staff like crap."

Aaaaand here's a picture of Lindsay giving her friend a little assistance (if you doubt it's her, check out the entire set):
