Brad Pitt was pictured for the first time since reportedly giving his estranged wife Angelina Jolie an ultimatum to sign their divorce papers or risk facing a 'financial sanction', as he ran errands in Malibu, California, on Monday afternoon.

Cutting a stylish figure, the screen star, 55, looked effortlessly cool as he sported black square-framed sunglasses for his low-key outing.

The Ocean's Eleven actor stepped out amid claims he is 'sick and tired' of actress Angelina, 44, 'stalling their divorce month after month', nearly three years after they made their decision to call it quits.

Opting for comfort, The Big Short star donned a maroon and white sweatshirt set, tied in with dark-wash jeans and slip-on shoes.

Father-of-six Brad accessorised his look with a baker boy hat and knitted handbag as he embarked on his trip around the Californian city with a pal.

The award-winning actor's outing comes after he allegedly encouraged his lawyers to ask the judge to finalise a deadline for Angelina to sign the papers, and put in place a hefty fine if she fails to do so.

In April, it was reported that Judge John Ouderkirk extended Brad and Angelina's court case until December 31, 2019.

And speaking of Brad allegedly going to great length to move on from the tainted marriage, a source has told The Sun: 'He has been incredibly patient throughout the divorce process despite being pushed to his limits on many occasions.

'But he’s finally had enough, and while he is a relatively calm person, he can only be pushed so far.'

Detailing Brad's plight further, it was continued: 'He’s sick and tired of Ange constantly moving the goal posts and stalling their divorce month after month - painfully dragging out the process which he now feels has become almost a game for Angelina.'

This has now reportedly resulted in Brad asking his legal team to liaise with the judge and put in place a deadline for the Gia actress to sign the papers, or risk facing a 'financial sanction if she fails to adhere to the date given by the judge.'

MailOnline contacted representatives for Angelina Jolie and Brad Pitt for further comment at the time of publication.

Angelina and Brad met on set of the 2005 film Mr And Mrs Smith, and wed in 2014 in France. In 2016 she filed for divorce. Nearly two months ago, it was reported by The Blast, that the pair are legally single.

Court documents were submitted that show a judge ruled on their bifurcation, which permits a divorce case to be finalised with certain aspects, such as property, to be dealt with after dissolution.

This comes after The Sun claimed that the beauty wanted to slow down the divorce process in hopes of winning back Pitt's heart.

'She would like them to be a family again and doesn’t seem capable of moving on,' a source claimed. 'That’s why she is making it so difficult for Brad with every detail of their divorce.'

The newspaper went on to report that Pitt wasn't interested in getting back together with his ex but did want to maintain an amicable relationship with Jolie for the sake of their kids.

In November of last year, Brad was granted joint custody of the six children her shares with Angelina.

Together the couple share six children Maddox, 17, Pax, 15, Zahara, 14, Shiloh, 13, and twins Vivienne and Knox, 10.

According to a new report from Us Weekly, the Troy star has settled in nicely to his new role as a single dad.

The publication even described his time with the children, noting he often cooks for them then they watch movies together at his home near Hollywood.

'They do simple things like cook or watch movies. He encourages them to pursue their hobbies. They love to hang out and talk. Brad talks to them about whatever is on their minds — he’s a great listener,' it was revealed.

Lately, the children have been spending a lot of time in New Mexico where Jolie is filming her latest movie, Those Who Wish Me Dead.

The children will reportedly travel back and forth between New Mexico and Los Angeles to visit their father.
