Nicolas Cage — The Dysfunctional Family Photo

Exclusive0515_nic_cage_family_photo_launchLooks 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 our sources “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 our sources “I want no contact with Christina Fulton and will never undergo the torment she put me through ever again.”

Most. Awkward. Photo. Ever.
