BRANGELINA MADE A RARE PUBLIC APPEARANCE AT AN ART EXHIBIT THIS WEEK...ONLY PROBLEM IS ANGIE'S ESTRANGED FATHER, JOHN VOIGHT, WAS ALSO IN ATTENDANCE! RUMOR IS SHE WAITED IN THE CAR FOR 30 MINUTES WHILE BRAD WENT INSIDE. ONCE VOIGHT SPOTTED PITT, HE RAN FOR THE DOOR AND ANGELINA ENTERED THROUGH A BACK ENTRANCE...
