Since Brad Pitt and Angelina Jolie's divorce news made headlines, new rumours and speculations regarding the former couple's high-profile marriage have been doing the rounds.

According to the latest report by TMZ, the Fight Club actor is preparing to file a law suit for the joint physical custody of his 6 children.

The gossip website's report suggested that the 52-year-old actor is set for a legal battle with his now estranged wife as he fights the original claim filed by Jolie seeking sole physical custody of the children with only visitation right allowed to him.

The news comes amid the recent developments in Brangelina's divorce drama with reports suggesting a meltdown involving the celebrity couple and their eldest son Maddox. Reports claimed that 15-year-old Maddox was struck during an alleged drunken row between Pitt and Jolie aboard a plane.

It was also reported that the LA County Department Of Children And Family Services (DCFS) launched an investigation after receiving an anonymous tip about the alleged incident.

Following this, the FBI released a statement saying it was, "continuing to gather facts and will evaluate whether an investigation at the federal level will be pursued".

As investigations unfold, a source close to the World War Z actor denied the claims made against him. "These claims are exaggerated and fabricated," the source said adding, "It's unfortunate for the whole family that people are insisting on continuing this endless smear campaign against Brad that hurts everyone."

"He takes the matter very seriously and says he did not commit any abuse of his children," another source told People Magazine. "It's unfortunate that people involved are continuing to present him in the worst possible light."

While Pitt will be represented by attorney Lance Speigel, whose clients include Michael Jackson, Charlie Sheen and Eva Longeria; Jolie's legal team consists of well-known divorce lawyers Laura Wasser and Robert Offer.

The Maleficent actress had initiated the divorce proceeding on 20 September after she filed for legal separation citing "irreconcilable differences" and requested to have sole physical custody of their children - Maddox, 15, Pax, 12, Zahara, 11, Shiloh, 10, and twins eight-year-old Knox and Vivienne.
