Green light means go!

HBO has given a green light to a fourth, 12-episode season of Entourage. The inside-Hollywood spoof about Vincent Chase and his posse of hanger-ons will return next year for the final 8 episodes of the interrupted third season. Good news for those of us who can't get enough of the friendly-banter between Ari and Drama!

MTV has also greenlit eight half-hour episodes of Adventures in Hollywood, a reality series that will tail Academy Award-winning rap group Three 6 Mafia. Umm...not really sure what this is going to be about, but expect a lot of haze and hoes!
