• On Tuesday TMZ added that they are indeed 'deep' in their divorce talks
• And it was also claimed the abuse allegations are keeping them apart
• There was talk Brad had hit one of the children, but he was exonerated

• Brad and Angelina announced their shock split in September 2016 

Brad Pitt is on the set of his new movie Ad Astra amid reports that his divorce from Angelina Jolie is very much still on. 

The 53-year-old actor was pictured hopping out of his trailer in Los Angeles wearing a green military shirt and tie preparing to film the futuristic sci-fi, which also stars Tommy Lee Jones. 

Brad was back to work as it was claimed last week's reports that the former Hollywood power couple have called off their divorce are false and that the duo are 'at the point of no return'.

On TuesdayTMZ insisted that the actors are 'deep' in divorce negotiations.

It was added that the 42-year-old Oscar winner and the 53-year-old Allied star will never get back together after allegations of abuse over one of their six kids - Maddox, 15; Pax, 13; Shiloh, 11; Zahara, 12; and twins Vivienne and Knox, nine - were made public.

'Both sides are hashing out both child custody and property settlements, and the divorce is full steam ahead,' a source told the site. 

And a reunion is not going to happen because 'Angelina made extremely damaging allegations against Brad, claiming he was abusive to their kids,' added the insider. 

In September 2016, there was an alleged 'altercation' that involved Brad and Maddox aboard a private jet that was heading from Nice, France to Los Angeles, California; after they landed, Angelina 'kicked him out,' according to Vanity Fair. 

Brad has since been cleared of any wrongdoing, but that was only after the FBI and DCFS were involved.

They have not been photographed together in a year. 

Last week Us Weekly claimed the former couple have not moved forward with proceedings to end their marriage.

One insider told the publication: 'The divorce is off. They haven't done anything to move it forward in several months and no one thinks they are ever going to.' 

The reason given for the alleged stall is Brad coming clean about his boozing in an interview with GQ this past May.

A friend of Jolie told Us Weekly that the commitment to self-improvement has struck a chord with the actress, who reportedly previously claimed she would consider taking Brad back 'if he showed he was committed to raising a family.'

The source went on to add that Brad had 'got sober to try and win her back' and that the move to quit drinking was 'all she ever wanted.' 

Meanwhile, the insider claims: 'Everyone thinks they are going to get back together. 

'It wouldn't be surprising if they announced that they're calling [the split] off and trying to work things out.' 

A source told DailyMail.com that the ‘divorce process has significantly slowed down but there has been no real change.'

The insider claimed that the former couple ‘are getting along for the sake of their children.'

The actor claimed to have gone cold turkey from alcohol and now sticks to sipping on cranberry juice and carbonated water in his GQ interview.

He admitted his drinking had been a problem and that his parenting style needed amending. 

The movie star confessed to entering therapy and has also been seen turning to art for healing, holing up in an LA studio to make sculptures. 

While partying at Glastonbury Festival in Somerset, south-west England, in June, Brad didn't touch a drop of alcohol because he was facing weekly testing by his legal counsel. 

A source told DailyMail.com: 'Brad didn't touch a drop of alcohol all weekend and stuck to drinking English breakfast tea. 

'He said he was being tested on a weekly basis by his legal counsel and didn't want to f**k up being able to see his children.'

Reps for both Angelina Jolie and Brad Pitt have been contacted by DailyMail.com in regards to the claims.

Angelina gave her first interview since separating from husband Brad in September 2016 to Vanity Fair for its September issue. 

The Maleficent star addressed the split revealing that 'things got bad' between the two by summer of 2016, adding that 'It's just been the hardest time, and we're just kind of coming up for air.'  

After filing for divorce, Angelina took the kids and stayed in a rental before purchasing a $25 million mansion in Los Feliz, California.  

The Lara Croft: Tomb Raider star said the new house was 'a big jump forward for us, and we're all trying to do our best to heal as a family.' 

The Salt star and Brad were together for 12 years before they announced their split in September; the divorce has not yet been finalized.

She is seeking sole custody of their children.  

Angelina and Brad, who became known as 'Brangelina,' met on the set of their film Mr. And Mrs. Smith in 2004 when Brad was still married to Jennifer Aniston. 

They married in an intimate ceremony on August 23, 2014 in Correns, France.

She told the magazine that her and her estranged husband 'care for each other and care for our family, and we are both working towards the same goal.'
