There were a number of surprising updates that followed in the wake of their split, including an alleged investigation by the Dept. of Children and Family Services into allegations of "abuse".
News of this comes after Jolie agreed with Pitt to seal the court documents pertaining to their custody battle.
Though it is unclear when the visit took place, over the New Year, the children were seen skiing and sightseeing with their 41-year-old mother in Crested Butte, Colorado.
Her lawyer Laura Wasser hit back in her own papers, obtained by TMZ, claiming the actor is trying to "deflect from (his) own role in the media storm which has engulfed the parties' children", and he's "terrified that the public will learn the truth".
The latest court filing mentioned that Pitt would do very little to cover private information from exposing it to the media, more so after the involvement of the Federal Bureau of Investigation and Dept. of Children and Family Services, making allegations on him for child abuse.
The FBI and DCFS probed claims of an altercation between Brad and teenage son Maddox on a private flight but FBI agents filed no charges and they closed the investigation, while DCFS officials cleared him of child abuse allegations.
In court documents obtained by PEOPLE, Jolie's lawyer Laura Wasser says Pitt has seen his younger kids at least once a week since October 8.
However, a second source has reportedly fired back, telling the publication that his behaviour might still have had a lasting impact on the children, despite the fact he was cleared in all investigations. However, Angie's source claims that his behavior may not be criminal, but it did leave the children "traumatized". "The kids are clearly traumatised, and Angelina has been protecting the kids by not revealing what really happened on the plane. Her interest since the outset hasn't changed: to protect the health and safety of the kids", the source added. As both actors have agreed to seal the documents of the custody case, the children are likely to get benefit from this decision.
