Brad Pitt is all smiles!
Amid his divorce from Angelina Jolie, the 53-year-old actor appeared to be in good spirits when he was spotted on the set of his latest film, Ad Astra, in Los Angeles on Monday.
Pitt was sporting a fresh 'do, looking dapper in an emerald green dress shirt and tie.
"He's very affable," a source tells ET, noting that Pitt's six children -- Maddox, 16, Pax, 13, Zahara, 12, Shiloh, 11, and 9-year-old twins Knox and Vivienne -- have not yet visited the set. "He comes to work in a good mood."
The James Gray-directed film follows the story of Roy McBride (Pitt), an Army Corps engineer who goes on a journey across the galaxy in search of his father, a renegade scientist who went missing in space 20 years ago. The sci-fi thriller also stars Ruth Negga, Tommy Lee Jones, Donald Sutherland and Jamie Kennedy.
"There's a pause in the [divorce] process because they both made children the priority, but nothing significant has changed in their relationship," the source explained. "Both have demonstrated great civility recently for their kids."
