E!'s Watch With Kristen is reporting that Zac Efron will be joining the Entourage gang for season six. Well, maybe not exactly joining the gang, but at least making a cameo on the HBO show.

Ok, so the question is, will he be playing himself? One of Ari Gold's newest It-Guys? An excitable young actor who tussles with Johnny Drama? My guess is that Efron will be playing himself, because he's becoming the Next Big Thing in Hollywood -- if he isn't already there.

And it just makes sense, because so many other stars have appeared as themselves on the show; notably, James Woods, though I've always wondered if he's as hot-headed as they make him out to be on the show. If so, he has quite the sense of humor about himself.

Last season on Entourage, when Vincent Chase decided to put his own money into Medellin it was a major risk and he knew it. He was rolling the dice on his career, taking a leap of faith by choosing to do a controversial biography of a vicious Colombian drug lord. In Spanish. Directed by a hot-headed genius/madman named Billy Walsh.

Vinney was playing with dynamite. It wasn't good for Vincent's career, but it was great for Entourage. Failure is always funnier than success, isn't it?

Well, as bad as viewers thought Medellin seemed to be based on the brief scenes we saw last season, in the September 7th premiere on HBO, the media weighs in. At the Movies' critics Michael Phillips and Richard Roeper filmed a fictional review of Medellin to be shown in season premiere of Entourage, and it's not good. In fact, if they were stilling using the thumb-o-meter, Medellin would get two big thumbs-down.

Have you been jonesing for the entourage from Entourage? Do you need a little Ari Gold to get your blood flowing? Well, new shows aren't coming back until September (thanks to the writers' strike), but HBO is giving fans a chance to enjoy the most recent shows starting tomorrow, July 4th. Every Friday at 10 p.m. (ET) on, HBO will replay season 3: part 2, and season 4.

That's good to know -- especially in these dog days of summer TV -- but if you want to know what's going to happen next, read on. Both Jerry Ferarra and Kevin Connolly, Turtle and E, got a little chatty with OK! magazine's Oliver Coleman.

If you don't want to know how things are going to unfold in season five, don't read after the jump.
