Angelina Jolie and Brad Pitt’s son Pax is out of the hospital following his scary accident. The 20-year-old was released from the ICU days after crashing his electric bike in Los Angeles, a source told PEOPLE on Sunday. The insider said that Pax — who Jolie, 49, shares with her ex-husband Pitt — “suffered complex trauma” in the crash.

“And now begins the long road of recovery and physical therapy,” the source added. Jolie rushed to her son’s side after he was hospitalized. The source said Pax and his mom “are deeply grateful for the quick and life-saving action of first responders, and the outstanding medical care he received.

” Pax’s five siblings have also “been visiting and helping” him since the accident. “They are all very close,” said the insider. Pax ended up in the hospital on July 29.

According to TMZ , he was driving his e-bike on Los Feliz Boulevard at 5 p.m. when he slammed into the back of a car that was stopped at a red light.

Pax, who allegedly was not wearing a helmet, injured his hip and his head, witnesses claimed. Medics reportedly feared Pax suffered a minor brain bleed in the accident, but TMZ reported that he was in stable condition at the hospital. Pax was adopted by Jolie in 2007 at age 3.

He was formally adopted by Pitt, 60, in 2008. The former couple , who were legally divorced in 2019, also share Maddox, 22, Zahara, 19, Shiloh, 18, and twins Knox and Vivienne, 16. Pax has a close bond with his mother.
