Party animals! Angelina Jolie and fiance Brad Pitt treated their six kids to a wild day at the zoo on Thursday, Dec. 26. The superstar couple and their famous brood -- Maddox, 12, Pax, 10, Zahara, 8, Shiloh, 7, and twins Knox and Vivienne, 5 -- enjoyed some quality time at the Currumbin Wildlife Park in Queensland, Australia, where they spent the holidays together earlier this week.

"They're used to celebrating wherever they're working," an insider told Us Weekly of the jet-setting family, who've been taking in the sights Down Under. (Jolie, 38, has been in Australia filming her new movie Unbroken.)

Clad in her usual head-to-toe black, the Maleficent actress looked casually chic as she and Pitt, 50, strolled through the zoo with their kids. They seemed to be in good spirits throughout the day; at one point, the A-list couple paused to pull Zahara in for a group hug.

The family also got up close and personal with many of the park's animals. Pax was even seen cradling a young kangaroo wrapped in a hot pink blanket.

The Jolie-Pitt brood has certainly been living it up in Australia over the past few weeks. On Monday, Dec. 23, they were photographed on a boat ride around the Coomera River in Queensland. And earlier this month, they rented the Ghost II luxury yacht in Sydney.

"They spent hours on the boat with the kids, who were really cute and friendly," an eyewitness told Us Weekly of the family. Added another insider: "They meet as often as they can. They don't want to spend too much time apart."
