First pics of Brangelina's twins

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."

For the complete story, including 19 pages of intimate family photos and the full interview with Brad and Angelina, pick up this week's issue of PEOPLE, on newsstands Monday.

The first photos of three week old fraternal boy and girl twins Knox Léon and Vivienne Marcheline Jolie-Pitt were supposed to premiere on People.com tonight at 7pm EDT. The magazine’s website has had red banner at the top of their homepage since Friday announcing the much-anticipated debut of the twins. At about 7:05 they removed the banner, though, with no explanation of when we could expect to see the first photo online. This has dissappionted a lot of readers.

They have a reported 30 freaking page {but now there are jus 19 pages} spread coming out in People tomorrow that cost the magazine $14 million, which was split with UK publication Hello.

Update: [The story is now up on People’s homepage nearly a half an hour after their announced release time, after it was posted then removed.]
