Ari's going to have someone new to bark at when Season 5 of Entourage starts up next month.

Executive producer Mark Wahlberg will be making his second guest appearance on the show, and this time he's coming for Jeremy Piven's hard-nosed agent, Ari Gold.

"I did one other cameo in the pilot, but I didn't get to do a scene with Jeremy Piven," Wahlberg told the New York Post. "This time it's me and Piven going at it, so it was fun."
