The "Brangelina" brood has been spending Christmas holidays Down Under and the kids have been spotted having boat fun with mum and dad, Brad Pitt and Angelina Jolie.

A series of photos published on Gossip Center showed the big family on a boat ride at the Coomeera River located in Queensland, Australia on Monday, Dec. 23.

Enjoying the Christmas cruis with “Mr. and Mrs. Smith” celebrity couple are Pax, Maddox, Zahara, Shiloh, and twins, Knox and Vivienne (age 5). Could it be a post-birthday celebration for Brad who turned 50 last week? The legendary Hollywood hunk was away working in London on his birthday while his family was away in Sydney. Angie continues with her directorial debut for biopic, “Unbroken.”

The “Inglorious Basterds” star may have reached a milestone on his birthday last week but an insider noted that Brad does not want to make a big deal of his 50th celebration.

"He's not doing anything for it and he said he doesn't want any surprises. He really doesn't want to talk about his birthday much,” says an insider in a report by Gossip Center.

The source added that he has plans to spend the weekend to celebrate his big day with his family.

“Brad said he's going to celebrate his birthday this weekend in Australia. That's going to be the only thing he does," continued the source.

The photos published by Gossip Center showed Brad indeed went to Australia to be with his family. He and Angie, along with the "Brangelina" brood have been spotted enjoying the Christmas cruise in a river in Queensland.

But the fun boat ride is not the only celebration that marks Brad’s birthday. His longtime partner, Angelina has brought him a heart-shaped island found in offshore New York with houses built by Brad’s favorite architect.

Angie and Brad have been together since 2005 after meeting on the set of the action-romance adventure film, “Mr. and Mrs. Smith.” Brad was still married to Jennifer Aniston whom he was married to for five years at the time he got romantically involved with Angelina. "Brangelina" as they are popularly known have been together for eight years. They have six children, Pax Thien, Maddox Chivan, Zahara Marley, Shiloh Nouvel, Knox Leon, and Vivienne Marcheline.
