Ben Affleck [1] and Matt Damon [2] are reunited — and it looks so good. On Monday, the longtime best friends hit the LA red carpet [3] at the season four premiere of their HBO show Project Greenlight, for which they serve as executive producers. True to form, the guys shared a few good laughs while posing for photos together. Matt debuted a new short 'do — yes, that ponytail [4] from July is gone — and opted for a casual look in a leather jacket and jeans. Meanwhile, Ben went all out in a blue suit. The 42-year-old also wore his wedding ring [5].

The photogenic duo's event marked their first appearance together since Ben and Jennifer Garner [6] announced their plans to divorce [7] on June 30. Although Ben avoided questions, People reports Matt gave an update on his buddy's mindset: "He's great, he's great. He's got a big smile on his face." Matt, 44, also touched on Ben's birthday on Aug. 15. "Yeah, I wish him well, but he's 43, it's kind of like, meh," Matt said. "What is 43? It's not 40, it's not 45, it's 43. It's a forgettable birthday."

In the midst of speculation about Ben's alleged affair with nanny Christine Ouzounian [8], the actor has continued to visit his children in Atlanta, where Jen is working on a new film project. Most recently, Ben reunited with his family [9] on Aug. 8. Read on to see Ben joke around with Matt on the red carpet.
