Brad Pitt BradPittBigSpender.jpgAngelina must really be lovin' her man now! While the Mr. & Mrs. Smith couple - along with each and every one of their kids - was visiting Chicago's Field Museum this past weekend, a museum guard let them all stay one hour past closing time. "They were a nice couple," says the guard, who was rewarded with a $300 tip from Pitt. Wow - no wonder he thought they were nice! Quite the generous amount, Brad. Hey, as long as you keep rakin' in all that box office money, might as well give some of it away!
