I am so happy Entourage is back. The show always has great celebrity cameos, and this season Matt Damon will make an appearance to promote the charity OneXOne.

Entourage executive producer Doug Elin told TV Guide. “It wasn’t hard to get him, Matt came on the phone with me and wanted to do something that focused on his charity, which helps kids all over the world.”

NBA star LeBron James will star with Damon in the episode where Damon forces Vincent Chase (Adrian Grenier) to donate more to the charity than he should.
