The actor, 46, is seeking treatment for alcohol addiction, according to TMZ.
The news comes just days after the Justice League star was photographed receiving an alcohol delivery outside of his Brentwood, California home.
The actor was seen accepting a delivery of what seemed to be Johnnie Walker Blue Label scotch whisky.
His first time in rehab was in 2001. In March 2017, Affleck announced that he had completed treatment for alcohol addiction.
“I have completed treatment for alcohol addiction; something I’ve dealt with in the past and will continue to confront,” he wrote on Facebook.
“I want to live life to the fullest and be the best father I can be. I want my kids to know there is no shame in getting help when you need it, and to be a source of strength for anyone out there who needs help but is afraid to take the first step. I’m lucky to have the love of my family and friends, including my co-parent, Jen, who has supported me and cared for our kids as I’ve done the work I set out to do. This was the first of many steps being taken towards a positive recovery.”
