He'll take on Jermemy Piven's character Ari Gold character in the show!

Move over Vince and Ari -- you've got company! Mark Wahlberg is set to cameo on "Entourage," says the New York Post.

"I did one other cameo in the pilot but I didn't get to do a scene with Jeremy Piven," he says, referring to the Emmy winning actor who plays combustible agent Ari Gold. "This time it's me and Piven going at it, so it was fun."

Wahlberg, who exec produces the popular HBO show, will appear during the fifth season, which kicks off next month.
