Brad Pitt recently spent time with all six of his children at his home in Los Feliz, California, a source close to Pitt tells ET.

"His kids visited him at his Los Feliz home on the evening of April 2," the source says.

According to our source, it had been a while since the six Jolie-Pitt children -- Maddox, 15, Pax, 13, Zahara, 12, Shiloh, 10, and twins Vivienne and Knox, 8 -- had been back at Pitt's home, quite possibly not "since the week before news [of the split] broke." The source notes that it has been quiet around the compound ever since, with the exception of some domestic help who are there daily.

On Saturday, 53-year-old Pitt was spotted making a visit to his art studio in Los Angeles. According to an eyewitness, his casual appearance was described as "skinny" and "disheveled." However, a source close to Pitt recently told ET that he "looks great" and has been working out regularly.

Last month, a source told ET that Pitt had been speaking directly to his estranged wife, 41-year-old Angelina Jolie, as their divorce has died down in the media, adding that the couple are focused on doing what's in the best interest of their kids. After an intense custody battle, Pitt and Jolie released a joint statement in January revealing that they were working with a private judge on their divorce case, and stated that they were "committed to act as a united front" moving forward.

"It's still in the process of being resolved," the source said of Pitt's and Jolie's divorce, noting that the two are making progress privately and properly.

"Brad knows Angelina is a really good mom," the source added.
