Brad Pitt recently rocked a beard while on a solo outing this week.

On Monday, Pitt, 55, looked scruffy as he headed out in Los Angeles, sporting a grizzled beard, gray pageboy cap, olive green tee, black jacket, and gray jeans. The actor accessorized his outfit with a cloth printed bag, white sneakers, and aviator sunglasses. Check out photos of Pitt's low-key outfit here.

It's not so surprising to see Pitt flying solo these days. Ex-wife Angelina Jolie filed for divorce in 2016 after having been in a relationship for a decade and married for two years. The ex-couple share six children together: Maddox, 17, Pax, 15, Zahara, 13, Shiloh, 12, and twins Knox and Vivienne, 10.

Meanwhile, Pitt's casual look seemed to be a contrast to his clean-shaven role in Quentin Tarantino's upcoming "Once Upon a Time in Hollywood." In the film, Pitt plays the role of Cliff Booth. He will star alongside Leonardo DiCaprio, Margot Robbie, Dakota Fanning, Al Pacino, Damien Lewis, Tim Roth and more.

While filming for "Once Upon a Time in Hollywood" has wrapped, it seems rumors about its stars are still rampant. One report recently claimed that Pitt has been turning to co-star Robbie for comfort amid his divorce from Jolie.

“Sometimes Margot is also a shoulder for Brad to lean on, as he has suffered horribly during his divorce,” a so-called source told OK! Australia. “He has told friends how kind she is and that she also has a brilliant mind, but people judge her too much on her looks.”

However, this report has been debunked by Gossip Cop, after the outlet confirmed from a source close to the situation that there is no truth to the rumors.

Robbie also told Porter magazine in a recent interview that she was barely on set during the filming of the movie and only had a few scenes with Pitt. Thus, it seems unlikely for the two to develop a "special bond" on the set.

"Once Upon a Time in Hollywood" is set to premiere in theaters on July 26.
