Angelina Jolie and Brad Pitt’s already famous newborn twins are already conquering the world.

The three-week-old babies, Knox Léon and Vivienne Marcheline, grace this week’s People & Hello magazines.

Angelina tells People, “It is chaos, but we are managing it and having a wonderful time.” However, Brad is quick to add, “[It's] still a cuckoo’s nest.”

The couple’s young girls, Zahara and Shiloh, love being big sisters and enjoy dressing up their new siblings. “[Shiloh] and Z pick out their clothes and help change and hold them. It’s sweet – they are little mommies.”

Brad tells Hello that the babies already have character. “Viv is proving to resemble Ange in spirit, attitude and physicality… And Knox, he’s a bit of me.”
