Aside from their box office hit movies, Brad Pitt and Angelina Jolie have been known in Hollywood for having a big family consisting of six kids - Maddox, 13, Pax, 11, Zahara, 10, Shiloh, 9, and Vivienne and Knox, 7.

Despite the challenge of trying to balance their Hollywood careers while raising their three adopted and three biological kids, there are rumors that Brad Pitt and Angelina Jolie are allegedly planning to expand their family further by adopting three more Syrian children.

"The Hollywood actress reportedly met up with three Syrian brothers who were orphaned after their father was taken away by soldiers and their mother killed in a bombing incident," Daily Mail reported.

Are Maddox, Pax, Zahara, Shiloh, Vivienne and Knox appalled that they will have three more siblings from Syria?

The Jolie-Pitt kids come from different backgrounds - Maddox is from Cambodia, Pax is from Vietnam, Zahara is from Ethiopia, while the rest are Brad and Angie's biological children - and raising them in one family with two very famous and busy parents is already a challenge in itself.

Throwing in three kids dealing with their biological parents' death and coming from another foreign background could up the challenge a hundred notches.

Is the Hollywood couple biting off more than they can chew?

According to a source, Maddox, Pax, Zahara, Shiloh, Vivienne and Knox need not worry. Brad Pitt purportedly convinced Angelina Jolie that adopting all three Syrian kids may be too much for their family.

"Angie wanted to adopt all three, but when she got back to the United States, and told Brad about it, he said no," an insider dished out to Radar Online, as quoted by Daily Mail.

"Going from six children to nine was just way too much, and Brad was concerned about how it would impact their other kids. But Angie didn't put up a fight. She knew it just wouldn't work. But they compromised at adopting one," the source added.

It is yet to be known how Brad Pitt and Angelina Jolie are going to choose who among the three brothers gets to be adopted into the famous family.
