A noticeably taller and lankier Maddox, 11, wore a baggy white T-shirt, black sweatpants and sneakers on his lunch outing with Pax, 9, and a bodyguard. The spunky youngster also showed off trademark blonde streaks in his stylish partially-buzzed haircut.
Little brother Pax, meanwhile, wore a Nirvana shirt and shorts and kept close by Maddox's side.
Jolie, 37, adopted Maddox from Phnom Penh, Cambodia, in 2002. She is also the adoptive mother of Pax, from Vietnam and Zahara, 8, from Ethiopia, as well as the biological mother of Shiloh, 6, and twins Knox and Vivienne, 4, with longtime partner Pitt, 49.
Last December, the Maleficient star admitted in an interview that she may have to scale back on her Hollywood projects as her kids get older.
"I think I'm going to have to give up acting as the kids hit the teenage years," she told Britain's Channel 4 News, explaining that there would be "too much to manage at home."
"I've enjoyed being an actress," she continued. "And I am so grateful to the job. I've had great experiences, and I have even been able to tell stories and be a part of stories that mattered. …It's a really lucky profession to be a part of. But if it went away tomorrow, I would be very happy to be home with my children."
