Brad Pitt and Angelina Jolie ... ACTUALLY TALKED TO US!!!
It all went down after the two had dinner at Boulevard3 in L.A. -- when BOTH superstars approached the photogs and chit-chatted it up.
Brad finally revealed why he refuses to sign autographs in blue ink ... and Angie pulled off one HUGE favor for one super-lucky fan.
Great up-close-and-personal footage of two of the biggest stars in the world -- check it out.
