Angelina Jolie and Brad Pitt's Kids Join the Cast of 'Kung Fu Panda 3'

Brad Pitt and Angelina Jolie, best known as two of the most talented and attractive people in Hollywood, have six children together from their over a decade-long relationship -- and now, Brangelina's kids are joining their famous mom in the animated sequel, Kung Fu Panda 3!

Entertainment Tonight recently released a small featurette of the upcoming movie, where Jolie is seen talking about the experience of making the film, and on it, she recounts that she took some of her children (12-year-old Pax, 10-year-old Zahara, 9-year-old Shiloh and 7-year-old Knox) to do voice work with her, even though they weren't too keen on the idea.

"They were kind of shy," Jolie told the outlet. "They don't really want to be actors, but I didn't want them to miss the opportunity. They came in, and they had a lot of fun with it."

Considering the job they had to do, it certainly does sound fun: the Jolie-Pitt children provided a few animal sounds for the project, which will be focused on Po (Jack Black) meeting his biological panda father, a story that resonated with Jolie on a personal level.

This isn't the first time the Jolie-Pitt children have taken part in one of their parents' projects, as their mom will often take them in to work for small parts when she's shooting.

According to People Magazine, Maddox is currently helping his Oscar-winning mom research for her upcoming film, First They Killed My Father: A Daughter of Cambodia and he also helped out his parents as a production assistant in last year's By the Sea, the first time Pitt and Jolie worked together since meeting on Mr. and Mrs. Smith.

Young daughter Vivienne also has a past in movies: in 2014, she played the 5-year-old version of Aurora in her mom's big Disney villain story, Maleficent.
