Maddox Jolie-Pitt seems to be taking right after his daredevil mom, Angelina Jolie: The 9-year-old celebrated his birthday by going go-karting with family and friends on Saturday.
A source told People that actress/pilot/stuntwoman Angelina, 35, and her partner Brad Pitt, 46, rented out Go Kart World in Carson, California, so that Maddox - who turned 9 on August 5 - could party in the park with brother Pax, 6; sisters Zahara, 5, and Shiloh, 4; and his pals.
Maddox and his guests spent the morning racing around the Mini Indy Track and chowing down on pizza and cake.
The kids had the best time, said the insider, adding that just like his Oscar-winning mom, the birthday boy nabbed an award. "Maddox even got a trophy at the end of the party for being such a good racer."
Although Maddox was showing off some choice behind-the-wheel skills, Jolie is glad he's still a few years out from getting a driver's license. "I'm not ready for them to driving, dating," the actress said. "I'm not ready for any of it."
But of course, every kid must grow up, and Jolie said she and Pitt plan "to just have a really, really great relationship with our children, so when they hit that time that they don’t want to talk to us, we've instilled some good values already."
