Fans were in for quite the surprise when Ben Affleck [1] popped up at CinemaCon in Las Vegas on Wednesday. The actor — whose divorce from Jennifer Garner [2] is still up in the air — joined the star-studded Justice League [3] cast, including Jason Momoa [4] and Henry Cavill, in promoting the highly anticipated film. Clad in a blue suit, Ben appeared calm and relaxed as he took the stage and posed for pictures with his costars.
The outing marks Ben's first public appearance since his rehab announcement [6], though he was spotted cracking up [7] with Jennifer during a family outing over the weekend. Ben recently completed a stint in rehab for "alcohol addiction," and according to his BFF, Matt Damon [8], things are on the up and up [9]. While doing press for Suburbicon [10] at the event on Tuesday, Matt said that Ben is feeling "fantastic" [11] since treatment and that he "couldn't be happier."
