Ben Affleck stepped in for his estranged wife Jennifer Garner’s duty of taking their three children to church on Sundays. Garner could not take the children to the church this time because she is attending the world premiere of her drama "Wakefield" at the Telluride Film Festival in Colorado.

Affleck was in casuals and sported stubble as he looked after the children, according to Daily Mail that posted pictures of the actor’s outing. The 44-year-old — who was in the U.K. shooting for "Justice League" — wore a black leather bomber jacket over an olive green T-shirt. He teamed it up with blue trousers and beige sneakers.

According to Daily Mail, Affleck returned to Los Angeles on Friday night.

Affleck’s former spouse Garner recently faced rumors about her fourth pregnancy after being spotted in loose-fitting clothes. However, neither of the two addressed the rumors.

Garner and Affleck announced their separation last June, ending 10 years of marriage. Since then, the two have been seen together on several occasions, leading to speculations that they are working to resolve their differences and getting back together. The two were also reported to have held off their divorce as they have not yet filed their divorce papers. However, those reports went unsubstantiated.
