Jolie-Pitt Twin Sighting — Check Out Knox and Vivienne in Venice With Brad and Angie!

Angelina Jolie and Brad Pitt kicked off the day by taking their four oldest children for gelato and a water taxi ride in Venice, but Vivienne and Knox were able to venture out as well. We last saw the twins during an ice cream run of their own in Syria last year, and it's amazing to see how much bigger they've gotten — and how much they look like Shiloh! Take a look at the youngest Jolie-Pitts in Italy with their parents!
