They are just 3 weeks old, but twins Knox Léon and Vivienne Marcheline are about to take the world by storm.

In an exclusive interview and photos, Brad Pitt and Angelina Jolie offer PEOPLE an intimate look at their growing family.

“It is chaos, but we are managing it and having a wonderful time,” Jolie tells PEOPLE of daily life at the Château Miraval in Provence, France, where the couple’s four older children – Maddox, 6, Pax, 4, Zahara, 3, and Shiloh, 2 – have been enjoying a summer of outdoor play (hide-and-seek is a favorite) on the château’s sprawling grounds.

Adds Pitt: “[It's] still a cuckoo’s nest.”

Fortunately, they already have some household helpers. “[Shiloh] and Z pick out [the twins'] clothes and help change and hold them,” says Jolie. “It’s sweet – they are little mommies.”

In an exclusive interview with OK!, Kevin’s attorney Mark Vincent Kaplan says both Britney and Kevin reached and signed off on a settlement in their custody case today. Kaplan tells OK!, “At about 8 p.m. PT, a final settlement in the Kevin Federline-Britney Spears custody case was signed. All parties have agreed to the following: Kevin will retain sole legal and physical custody of Sean Preston and Jayden James. Britney will continue to have visitation rights which may increase over time. The agreement will be presented to the court in the morning for approval by the commissioner.” Kaplan adds, “Kevin is ecstatic and the boys are thriving.”

“It hasn’t totally sunk in,” Jessica reveals to OK!. “She dreams, she smiles, and coos and does all these things, but she hasn’t seen enough of the world yet to understand any of that stuff. So I still feel like she’s connected to the other world, or something. There’s no other way to explain it. It’s a miracle.”

“She’s not drinking. It’s the first time I’ve never seen her do that.” Above source is a firsthand, regular and up close observer of Paris Hilton and her horniness, hotness and sometimes tankedlicious goings on. Said insider’s been posing and preening right alongside Ms. H at a few recent T-town soirees. Gosh, is this the new, freshly domesticated Mrs.-Madden-to-be Paris or Paris the teetotalist, perhaps (for whatever reason)? Or, to get very National Enquirer about it (as if there were any diff here at A.T., I mean, really), could this possibly be the new preggers Paris? Just a pregnant pause, or hunch, that’s all, babes. See, when the regularly guzzling heiress suddenly cleans up her vodka-happy act, hon-pies, somethin’s up. Fer sure.”

On the labor and delivery…
“They’d told me it would be an eight- to 12-hour labor, and I was ready to have the baby in three to four hours,” Jamie Lynn tells OK!. “I had a perfect pregnancy and a perfect delivery. I was very blessed. Once I got in there, my doctor was just so calm and so good it was not bad at all,” she says. “I was just talking to Casey. And you know what’s so weird? I was asking him if he was okay. He was like, ‘Yeah.’ We were both so excited.”

On taking care of Baby Maddie…
For now her proud parents like having her next to them at night, so she sleeps in a bassinet in the same room as Jamie Lynn and Casey. “She is very good,” says Jamie Lynn. “She’ll feed every two or three hours. When she wakes up in the middle of the night, I’ll feed her and she goes right back to sleep. There’s no screaming and crying.” The proud mama continues, “We get up in the morning, and she gets her little bath. Then I get my bath. We have a routine, and I love routines. I’ve worked one out with her, and we’re happy going about our little life.”
