“High School Musical” and “17 Again” star Zac Efron is set to make a cameo appearance on HBO’s Entourage in their upcoming season according to my sources. He was seen filming his cameo scenes yesterday (6-2-09) at the Niketown store in Beverly Hills according to one source. He was apparently filming a scene while talking on his cell phone according to one of the Niketown employees. None of the other cast members from “Entourage” were there,but they said that Zac was really nice.

Other big names that are slated to appear on “Entourage” this season are Tom Brady, Lil Wayne, and LeBron James. Kevin Dillon who’s an Entourage regular,said it wasn’t always easy to get celebrities to appear on the show,but then after they got Val Kilmer to appear, it became pretty easy. “Entourage” 6th season is supposed to start airing July 12,2009 on none other than, HBO.
