But this wasn't just any shopping spree -- Angelina Jolie bought her twins Knox and Vivienne a bunch of books at Barnes and Noble! #summereading...

As usual, Angelina wore all black (save for those nude ballet flats), and Vivienne wore an adorable dress and showed off her long locks while Knox kept it casual in a pair of khakis and a t-shirt. Wonder if Vivi is raiding big sis Zahara's closet these days? She's certainly not borrowing anything from Shiloh!

Earlier this week daddy Brad Pitt stepped out in Los Angeles and revealed his latest tattoo, which pays tribute to Angie and the kids. He know has a large cross on his forearm with an A for Angelina on one side and S, Z, M, P, N and V on the other for all of the couples six kids. Awww!
