In an Entourage episode filmed just days ago, porn performer Tommy Gunn plays the role of male talent at a photo shoot where he encounters his ex-girlfriend — Sasha Grey. Grey appears on the show as herself —and her new boyfriend, Vince Chase, a lead character, is played by mainstream actor Adrian Grenier.

“My appearance was brief, but I did get some dialogue with the lead characters,” Gunn told www.xbiz.com. “In the scene, I play Sasha’s ex and there’s a lot of tension while she introduces me to her new boyfriend.”

Gunn’sappearance marks his debut in mainstream.

The episode’s air date is yet to be announced.
