Angie & the Twins: First Days at Home

In the wee hours of the morning on July 19, Brad Pitt and Angelina Jolie's adorable twins, Vivienne Marcheline and Knox Leon, quietly exited Fondation Lenval Hospital in Nice, France, and were welcomed home by their four siblings at Château Miraval in Brignol.

"Everyone is so excited about the twins," an insider tells OK!.

Indeed, the littlest Jolie-Pitts, who were delivered on July 12, were greeted at the $60-million castle by gifts sent from all over the world — plus a few items that Brad, 44, and Angelina, 33, picked out on their own!

"They bought quite a lot of baby clothes," Audrey Arbibe, owner of children's boutique Bonpoint, tells OK! exclusively of the couple's impromptu May 19 spree in Cannes, France. "Mostly beiges and whites. Angelina has very elegant, yet natural, taste — nothing frilly."

Frills, or no frills aside, six children is a lot to handle — especially when you add newborn twins into the mix! Angelina's brother, James Haven, and Brad's parents, Bill and Jane Pitt — who looked on as their grandchildren played soccer on the grounds of the palatial 1,000-acre estate over the weekend — flew to France for the birth of the newest Jolie-Pitt members, and, according to an insider, "They're sticking around to help everyone get settled into the new routine."

Still, it's not like motherhood is a role that Angelina hasn't already mastered. Jason Butler Harner, her co-star in the upcoming thriller The Changeling, observed the actress with Maddox, Pax, Zahara and Shiloh during filming, and tells OK!, "She's calm and has a sense of humor. You would think it takes a village, but it's just her."
