Finally some good news!

Rumors have been going around that Ben Affleck isn't being cooperative in rehab and not taking his recovery seriously, but his younger brother Casey just put those to rest.

“He’s doing great. He’s in rehab and he’s recovering and seems to be doing well," the Manchester by the Sea star told ET at the Toronto Film Festival on Monday.

"I think he’s holding up, taking some time for himself, his family. He’s going to be OK. He’s a great guy, and he’s going to get things back on track," he echoed to Extra.

Last year, Casey admitted on the WTF with Marc Maron podcast that he was three years sober, and that alcoholism runs in their family, so he's a good source of support for his Batman bro!
