Brad and Angelina's German Jaunt

Is the most jet-set couple in Hollywood overdoing it a little?

After a frail-looking Angelina Jolie joined Brad Pitt for a half-hour stint on the red carpet of the German premiere of The Curious Case of Benjamin Button in Berlin on Jan. 19, the parents of six skipped the afterparty at the Sony Center’s Imperial Hall.

This left many to wonder if their constant balancing act — juggling career, kids and coupling — has left them exhausted.

“Brad and the boys hung out at the indoor climbing park and loved it,” Uta Zoldann, marketing manager of Legoland Discovery Center in Berlin, tells OK! exclusively.

During their three-hour visit, Angelina, 33, played with her two eldest daughters. “They were in the playground,” adds Uta.

“Angelina went down the slide many times with the girls and looked so happy.”

The children’s favorite attraction at Legoland Germany? “Building a super-fast Lego car at the build-and-test station,” says the park’s Uta.

The following night, Brad and Angelina left the children at the Ritz Carlton for a relaxing date night at Vina a Cucina in Berlin’s Mitte neighborhood.

But the action doesn’t stop there! Next up for the traveling family: St. Petersburg, Russia, where Angelina has pre-production meetings for her next film, the spy thriller previously known as Salt.

Phew! We need a vacation just thinking about it...
