Ben Affleck recently completed a rehab stay for alcohol addiction, and according to his BFF Matt Damon, things are on the up and up. In an interview with ET on Tuesday, Matt said that Ben is feeling "fantastic" since treatment and that he "couldn't be happier." He also added that Ben's "with the kids now" while estranged wife Jennifer Garner is away filming her upcoming movie Simon vs. the Homo Sapiens Agenda. "Jen's working for a couple weeks in Atlanta, so he's Mr. Mom-ing it right now," Matt said, adding, "And that's what he wants to be doing."

More evidence of Ben's upswing came from the same outlet earlier this month, which reported that the Oscar winner is "feeling good" and that he "wants his kids [daughters Violet and Seraphina and son Samuel] to know that he did everything he could to be a better father."
