Looks like hell officially froze over ... Nicolas Cage, his baby mama and their alleged wife-beating son all hung out together for FUN on Monday night ... which NEVER happens.

Weston Cage had a gig with his metal band at Whiskey a-Go-Go in Hollywood ... when surprisingly his mom -- Christina Fulton -- and famous dad showed up to cheer him on ... even though the family is as functional as the Greek economy.

But this time was different ... the happy fam snapped a pic (above) ... and we're told no one got hurt.

So, we recapped some of their past hobnobs ... just to see how far they've come.

-- Nic Cage and baby-mama Fulton hit up a courthouse to settle a nasty $13-mil lawsuit
-- Nic tells TMZ "I hope Ms. Fulton will come to her senses one day and get some help."
-- Nic sends an employee to hunt down Weston ... who then beats the crap out of him. 
-- Weston is taken for a "mental evaluation," but his mom is banned from the hospital.
-- Fulton tries to get conservatorship of Weston ... against his wishes.
-- Weston tells TMZ "I want no contact with Christina Fulton and will never undergo the torment she put me through ever again."

Most. Awkward. Photo. Ever.

Nicolas Cage once spent himself into "financial ruin" by blowing cash on all sorts of stuff he didn't need (like a "flotilla of yachts" and a pyramid of death) ... but according to his son, Weston -- he made one smart investment ... A FREAKIN' SABER-TOOTHED TIGER SKULL!!!

Seems Nicolas Cage is finally over that whole "financial ruin" thing -- 'cause dude just dropped TWO THOUSAND DOLLARS on a steak knife in Alaska ... TMZ has learned.

Nic was chillin' in Anchorage Wednesday -- when he rolled into a bad ass custom blade shop called Northern Knives.

We're told Cage fell in love with a Don Dezarn original -- which featured MAMMOTH IVORY in the handle and a patriotic bald eagle engraved onto the 4-inch blade.

The knife is primarily used as a decorative piece, and one knife expert tells us it's common for people to wear similar blades as a holstered accessory with a "nice suit."

Knife experts tell us ... $2,000 is pretty reasonable for a knife of that caliber. But the crazy part ... Nic told people inside he plans to use his fancy shank to cut his steak!!!

Chew on that.

Looking like a homeless hipster longshoreman, Nicolas Cage hit up an ATM for some cash while in Glastonbury, England on Wednesday.

Despite massive debt, getting arrested for domestic abuse but having the charges dropped earlier this year and his son Weston's issues, the bearded 47-year-old still manages to look at life through TWO pairs of rose, er, orange-colored glasses.

Weston Cage was arrested early this morning by LAPD for felony domestic violence ... for the second time in a MONTH, TMZ has learned.



Law enforcement sources tell TMZ, Weston was arrested at 5AM in Hollywood -- and then taken to a nearby hospital to be treated for cuts ... and we're told, cops believe the injuries were self-inflicted.

TMZ spoke with the mother of Weston's wife Nikki Williams -- who tells us, "Nikki is safe and away from him."

It's the second time in a month Weston's been popped for domestic violence -- except last time, Nikki was also arrested ... after allegedly going after Weston with a bottle.

According to the L.A. County Sheriff's website, Weston is still in custody on $50,000 bail.

Story developing ...

Kimbo Slice is laughing off Weston Cage's challenge to step into the octagon -- but he's still more than willing to take the son of Nic.

Weston told TMZ ... his dream MMA battle would be against Kimbo ... a former MMA star who switched to boxing.

Kimbo's rep, Jared Ryan Shaw, has serious questions about Weston's state of mind: "Mental stability would have had [Weston] think twice about his wishes to fight a street certified, cage tested, and boxing ring ready Kimbo Slice." 

Shaw also jabbed,  "Kimbo is Nic Cage famous ... and Weston's 15 minutes are up."

Tough talk aside, the rep says Kimbo's happy to fight Weston ... but only in a boxing ring.

Your move, Weston.

It may be the quickest resolution ever of a lawsuit -- but a day after Nic Cage was sued for $77,176 by a big-shot movie producer, the case has gone away.



We're told the dispute between producer Paul Brooks -- who worked with Cage on "Shadow of the Vampire" -- has been resolved.

Cage's rep tells TMZ ... "Contrary to recent reports that a lawsuit was going forth by Paul Brooks and Early Bird Productions against Mr. Cage, this matter has been resolved privately and amicably between the parties and therefore no legal action is being pursued."

Sources connected with the case tell TMZ .. the lawsuit will be formally withdrawn on Tuesday.

A big Hollywood movie producer has apparently been grousing that Nic Cage stiffed him on a vampire film years ago, and now he's filed a lawsuit to settle the score.



Early Bird Productions, the movie company that produced "Shadow of the Vampire" back in 2000 claims in a new lawsuit that Paul Brooks -- whose producer credits include "My Big Fat Greek Wedding" -- was owed at least $77,176 for his services and Nic was obligated to pay. 

The suit alleges Nic never anted up the dough, so 11 years after the movie was made, Early Bird is asking a judge to make things right.

Has Early Bird ever heard the expression, "Get in line?"

No comment so far from Nic's camp.

The guy who beat the crap out of Nic Cage's son Weston got a restraining order against Weston claiming he's the victim of harassment ... though it seems to us he can take care of the threat on his own.



Kevin Villegas -- who worked for Nic Cage -- punched the living daylights out of Weston in Hollywood earlier this month after Weston allegedly tried to attack him with a roundhouse kick. Cops responded to the scene -- strapped Weston to a gurney and took him to a hospital for a mental evaluation.

After the fight, Villegas filed a request for a restraining order against Weston -- calling him "mentally unstable" and claiming Weston issued "threats of violence" against Villegas and his family at the time of the fight.

A judge granted the restraining order -- requiring Weston to stay at least 100 yards away from Villegas and his family at all times.

FYI -- Villegas never served notice on Weston before the hearing ... nor has he informed Weston that he got a restraining order.

Nic Cage is scoffing at his baby mama's attempt to get a conservatorship over their son, Weston, telling TMZ, "I hope Ms. Fulton will come to her senses one day and get some help."



Christina Fulton and Nic are in court today ... trying to settle her $13 million lawsuit claiming Cage didn't give her the home he promised, causing her emotional distress. 

Outside the courtroom where the settlement conference is taking place, Christina mouthed off that she was taking legal steps to get a conservatorship for Weston by the end of this week.

Weston Cage had gone missing last week in the hours before he went off the hinges and had to be subdued by cops ... and the guy who had to beat him down had been sent by Nic Cage to find him.



The one-man search party was 39-year-old Kevin Villegas (left) -- who worked as an assistant for Nic Cage for the past 5 years. We're told Kevin's primary responsibility was looking after Weston.

But Tuesday, when Weston went M.I.A -- sources tell us Nic dispatched Kevin to track down the 21-year-old and bring him home. Kevin quickly located his target in L.A., but we're told, Weston was resistant and aggressive -- even threatening to rip off Kevin's "Christian f**king head."

Sources tell us Kevin immediately reported the situation to Nic ... who instructed Kevin to call 911. When Weston realized cops were on the way he flipped out and attacked Kevin with the roundhouse kick.

We're told Kevin -- who served with the U.S. military -- feared for his life because Weston is a highly-trained fighter ... and attacked Cage with a flurry of punches.

Cops came and Weston was hospitalized for a mental evaluation. Weston says he may press charges.
