Angelina Jolie and Brad Pitt's son was in an accident on his electric bike.
Pax Jolie-Pitt crashed into a car on busy Los Feliz Boulevard in Los Angeles on Monday night.
According to TMZ , the 20-year-old was driving down the boulevard when he crashed into the back of a car at an intersection.
Police determined that Pax was not wearing a helmet and therefore suffered a head injury.
Paramedics arrived at the scene, where Pax complained of pain in his hip and head.
The victim was rushed to a Los Angeles hospital.
Doctors found a small bleed in the brain, but Pax's condition remains stable.
He is expected to be discharged home soon.
Pax, the fourth of Jolie and Pitt's six children, rides a BMX-style electric bike without a helmet.
Perhaps a helmet would have helped him in this accident.
