Knox Jolie-Pitt is starting to look more and more like Brad Pitt's Mini-Me.

Brad and Angelina Jolie's adorable four-year-old son had some swag in his step as he headed out with his family to the Natural History Museum on Valentine's Day, dressed just like his 49-year-old dad.

Sporting all black from head to toe, Knox mimicked his dad's outfit, rocking sunglasses, a blazer, T-shirt and matching pants. Brad, also was wearing all black for the family day, donning a coat, T-shirt and jeans as well.

Brangelina took Knox and his twin sister Vivienne to the Natural History Museum in Los Angeles, where the young duo were smitten with the dinosaur exhibits.

A source told E! News the tiny tykes had a blast playing with fossils, putting together a Tyrannosaurus Rex puzzle and looking at specimens through a microscope while they were there.

They grow up so fast. And so cute!
