Brad Pitt is reportedly ‘upset and aware’ that his daughter Shiloh filed to drop his last name from her own on her 18th birthday.

A source close to the 60-year-old Oscar winner said his erasure from his daughter’s life is just another indication that he has ‘lost his children,’ according to People.

‘He’s aware and upset that Shiloh dropped his last name,’ the source claimed. ‘He’s never felt more joy than when she was born. He always wanted a daughter.’

Notably, Pitt was already in the process of legally adopting a daughter who had been a part of his life for months before he and his then-partner Angelina Jolie, 49, had announced she was pregnant with Shiloh in January 2006.

Jolie had traveled to Ethiopia to adopted her first daughter Zahara, 19, in July 2005, and Pitt had come with her on the trip.

He was reported to be in the process of becoming Zahara’s adopted father in December 2005, a month before he and Jolie announced her pregnancy.

‘The reminders that he’s lost his children, is of course not easy for Brad,’ the source continued. ‘He loves his children and misses them. It’s very sad.’

They added that the distance between Pitt and his six children — Maddox, 22; Pax, 20; Zahara; Shiloh; and twins Knox and Vivienne, 15 — ‘pains him.’

However, they noted that ‘he’s still happy with Ines [de Ramon],’ his girlfriend.

Another source described as close to Pitt told the publication that the Tree Of Life star ‘still loves all of his kids tremendously.’

‘This whole process has been very hard for the whole family,’ they added.

If Shiloh’s request is granted — and there is no indication that it would not be — she will subsequently go simply by ‘Shiloh Jolie,’ rather than her original full name, ‘Shiloh Jolie-Pitt.’

People previously reported that Pitt’s youngest daughter Vivienne — who served as her mother Angelina Jolie’s assistant when she produced the Broadways musical adaptation of The Outsiders — had listed her name as ‘Vivienne Jolie’ in the Playbill for the show.

It is unclear if Vivienne has legally changed her name, but the minor would likely need either parental consent or extenuating circumstances to be allowed to do so before turning 18.

Zahara previously introduced herself as ‘Zahara Marley Jolie’ when she joined the Mu Pi chapter of the Alpha Kappa Alpha sorority at Spelman College late last year.

Pitt and Jolie’s oldest sons, Maddox and Pax, have reportedly not publicly used their father’s last name in years, and both have been openly antagonistic toward him.

Pitt and Jolie began dating publicly shortly after he and his then-wife Jennifer Aniston announced their divorce in 2005.

The Mr. And Mrs. Smith costars remained unmarried for years despite having multiple adopted and biological children together, but they got engaged in 2012 and finally tied the knot in 2014.

However, it was only around two years later when the Maleficent actress filed for divorce in 2016. She and Pitt were declared legally single in 2019.

However, the two A-listers have been embroiled in an ongoing divorce battle over assets and custody for years since.

A central issue seems to be a notorious private jet confrontation in 2016

Pitt has been involved in an ongoing divorce battle for years, seemingly stemming from a 2016 incident on a plane in which Jolie accused Pitt of assaulting her; the family seen in 2011

An FBI report on the incident, which was published in 2022, saw Jolie accuse Pitt of physical assault while flying to California in 2016. She claimed that he was intoxicated and that he grabbed her by the head and shook her, and later pushed her down, as part of a confrontation allegedly related to their children.

Jolie told the FBI that Pitt told the children that she was ‘f***ing up this family,’ and she said he punched the ceiling of the airplane four times.

She claimed that at one point he poured beer on her and a blanket she was under with multiple children.

Source close to Pitt later claimed that he never hit any of the children, though they admitted that he had been drinking.
