Is Ben Affleck back to being a hot mess?

To the untrained eye, it appears Ben Affleck was channeling his inner Britney 2007 over the weekend. But not so fast, says a friend. Despite leaving a “Suicide Squad” premiere with his zipper down and shirt tucked into his belt, we’re to believe that Affleck — who remains estranged from wife Jennifer Garner because the world is a vampire and everything you know about love is a lie — has things under control. “That picture is outside another small after-after-party,” the source tells Page Six. “It was very late at night. He’s not off the rails. It looked a lot worse than it was.”We’re rooting for you, Ben — but if you shave your head, we’re calling your mom.
