AceShowbiz - On August 11, Angelina Jolie made her first public appearance since her son Pax's harrowing e-bike crash on July 29. Spotted at Los Angeles International Airport, the 49-year-old mother-of-six was dressed in an all-black outfit, concealing her face behind large sunglasses.

Pax, 20, was released from the ICU earlier this month after suffering a complex head trauma in the accident. Despite not wearing a helmet, he is considered fortunate not to have sustained more serious injuries.

Sources close to the family reveal that Angelina was "shocked and worried" upon learning of Pax's accident, with her other children also rallying around him. However, Brad Pitt's involvement has been limited due to his estrangement from Pax and the ongoing conflict between him and Angelina.

An insider told DailyMail.com that Brad is "distraught" over his inability to contact Pax, who has reportedly "shut him out" and has no desire for his well-wishes. The source added that Brad feels "gutted" because he is unable to fulfill his role as a father during this difficult time.

The accident has reignited tensions between Angelina and Brad, who are still embroiled in legal battles over their French winery. Sources indicate that Brad believes Angelina has "poisoned" the children against him, further straining familial ties.

"Brad would love to be there more for Pax, and all the kids, but she's managed to turn them against him so much he's practically out of the picture," an insider told InTouchWeekly. "From Brad's perspective it's absurd for her to try to put any sort of blame on him. She's the one who's there day to day, he's barely around because she's totally shut him out and poisoned the kids against him."
