Angelina Jolie and Brad Pitt's daughter Vivienne appears to drop dad's last name

Angelina Jolie and Brad Pitt's daughter Vivienne appears to have dropped the 'Pitt' from her last name.

The 15-year-old's famous parents have been locked in a messy legal battle following the breakdown of their marriage in 2016, and the most recent claims come regarding the sale of a French winery they purchased when they were together.

New papers submitted to the Los Angeles Superior Court in April also contained some bombshell accusations.

A lot of it detailed alleged abuse by Pitt - something the actor has categorically denied.

In recents weeks, Jolie has also accused her former partner of ‘unrelenting efforts to control’, as well as accusing Pitt of trying to 'bleed her dry'.

A source familiar with the situation added: "Angie says Brad is bleeding her dry – but it looks like she wants to bleed him dry.

"Far from being out to ruin his ex, it looks like Brad has bent over backwards to support Angie and help her out financially in spite of her appearing to be so vindictive."

However, the Daily Mail reported that Jolie’s relationship with Pitt has helped enrich her by close to $100 million.

The paper also reported that this money has come through loans, child support and gifts.

Now, it has emerged that one of the pair's children has dropped Pitt from her surname.

15-year-old Vivienne is one of Jolie and Pitt's six children, and helped her mom produce the new musical, The Outsiders.

As per PEOPLE, the former couple's daughter was listed as Vivienne Jolie in the Playbill, instead of Vivienne Jolie-Pitt.

It's unclear at this time whether Vivienne has legally changed her name.

UNILAD has reached out to Jolie and Pitt's representatives for comment.

Vivienne is not the first of Jolie and Pitt's children to go by a name change in recent years, as the former couple's eldest daughter Zahara introduced herself as 'Zahara Marley Jolie' in a video shared by Essence last November.

With Vivienne seemingly changing her name, it's yet another twist in the Pitt-Jolie saga.

In newly filed court documents obtained by the Daily Mail, it has been claimed: "It is extremely painful for Jolie to have to defend herself from Pitt's lawsuit – itself another example of Pitt's unrelenting efforts to control and financially drain her – especially because Pitt's false allegations as to the reasons the Miraval deal cratered can only proven by doing exactly what Jolie never wanted to do: Provide to the trier of fact the reason the Miraval deal failed, which was Pitt's demand for an NDA to cover up his history of physical and emotional abuse of Jolie and their family."
