ANGELINA Jolie and Brad Pitt’s son Maddox made a rare outing in LA after “testifying against his dad in his parents’ custody battle.”

The famous former pair have been fighting in court since their official divorce filing in 2016.

Maddox was spotted out for lunch with a friend at Wurstkuche in West Hollywood.

Maddox, who wore a black sweatshirt and matching sweats with a beanie, donned a mask before sitting down for lunch with his pal.

The duo were said to each have a Ginger beer during their outing together.

However, while Maddox looked like he was having an easygoing day, it comes just a few weeks after the college student testified against his father during his parent’s custody battle, which is currently in its fifth year.

A source previously told Us Weekly: “Maddox has already given testimony as [an] adult in the ongoing custody dispute and it wasn’t very flattering toward Brad.

“He doesn’t use Pitt as his last name on documents that aren’t legal and instead uses Jolie. Maddox wants to legally change his last name to Jolie, which Angelina has said she doesn’t support.”

Brad and Angelina share six children: Maddox, Pax,  Zahara, Shiloh and twins Knox and Vivienne.

Early last month, the A-list actress filed new court documents that alleged of “domestic violence.”

The Sun confirmed that Angelina filed court papers to “offer proof and support” of “testimony regarding domestic violence.”

The actress made no indication the “domestic violence” matter mentioned in the documents was related to her estranged husband, while she also offered “proof” in support of their minor children testifying at trial.

An insider told Page Six that the Once Upon A Time in Hollywood star was “heartbroken” after his ex-wife’s “abuse” claim.

Angelina filed for divorce from Brad in September 2016, citing irreconcilable differences – Daily Mail previously reported that legal experts in Los Angeles say the ex pair have already spent over $1 million in legal costs.

After the mother of six filed for divorce, it was reported that Brad was allegedly involved in an incident with Maddox while on a private jet.

At the time, witnesses claimed Brad flew into a drunken rage on the plane and “got physical” with eldest son Maddox.

Witnesses said Brad was “out of control” and allegedly clashed with the then 15-year-old.

Following a review, the FBI and Los Angeles County Department of Children and Family cleared the actor of any wrongdoing.

Angelina’s father, Jon Voight, previously exclusively told The Sun about his daughter’s custody battle and his thoughts on her ex.

He said: “[Brad] has had some difficulties with alcohol and I hope that he takes care of things and I pray for the guy. The kids are coping as best they can.”
