The 45-year-old actor, who began his treatment for substance abuse in Los Angeles, took permission to freeze his plan so that he could spend Christmas with his estranged wife Jennifer Garner and children - Violet, 12, Seraphina, eight, and Samuel, reports Pagesix.com.
After their separation in 2015 and divorce filing in April, the two actors have amicably continued to co-parent their kids.
He was also spotted with his girlfriend, Lindsay Shookus, at Nobu in Malibu, California and according to sources, the actor stayed sober during the meal and is expected to return to his rehab facility for further treatment.
Previously, the 'Justice League' star posted a note on Facebook stating that he was seeking help for his issues in order to show his kids there is "no shame" in getting help.
He wrote at the time: "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."
On the work front, the 'Argo' star is undergoing a new rehab treatment ahead of filming 'The Batman' in 2018, where he will return as the Caped Crusader after playing the character in the recent 'Justice League'. (ANI)
