It was bound to happen sooner or later.
Pitt, 47, took four of his children with Angelina Jolie -- Maddox, 10, Pax, 8, Zahara, 6, and Shiloh, 5 -- to see the 2:00 showing of Martin Scorsese's "Hugo," starring Chloe Moretz, Sacha Baron Cohen and Jude Law.
Once the family flick ended, Pitt and his brood headed to the parking garage just as Aniston, 42, and current love Justin Theroux entered the theater for a later showing.
"Justin and Jennifer skipped the popcorn and went straight in. Like five minutes later, Brad and the kids came out of the theater," a source tells X17. "They just missed each other!"
Perhaps it was a good thing the ex-spouses managed to steer clear of each other. "They don't talk," an Aniston insider told Us Weekly in September. "She will always think of him as a jerk."
