The ever-engaged couple brought twins Knox and Vivienne to Los Angeles' Natural History Museum, where the favored attraction for the 4-year-olds turned out to be—no surprise here—the dinosaurs!
"Brad at one point was overheard telling a staff member they wanted to come see the new Dinosaur Hall, and they definitely saw a 'Dinosaur Encounter' show," which features a life-sized Tyrannosaurus rex puppet, a source tells E! News.
The insider says the family didn't give off any needing-special-treatment vibes and just seemed like "the coolest people."
We hear that Knox and Vivienne had a blast playing with fossils, looking at teeny-tiny specimens through microscopes and putting together a T. rex puzzle in the Dinosaur Hall's discovery center.
Sounds like Brad and Angie had a Valentine's Day for the ages.
