He stopped to sit down and take a phone call before heading home.

The next day, Josh stepped out for a solo coffee run before taking his and Fergie‘s four-year-old son Axl (not pictured) to a birthday party.

The father-son duo reportedly got a caricature made of them!

Josh was not wearing his wedding ring during his outings, as he and Fergie announced last week that they separated earlier this year. The couple rang in eight years of marriage back in January and celebrated in Hawaii.

Josh has been busy working on his upcoming movie The Buddy Games. See the latest set photos here.
