Jessica Simpson on Entourage Season 7

Pacific Coast News

After filming The Price of Beauty, Jessica Simpson said that she finally learned how to just be herself -- and for her upcoming guest spot on Entourage, she's taking that lesson literally! Simpson, 29, will join the elite group of celebrities who've played themselves on the HBO show, now entering its 7th season. Photos from the set show the singer-actress greeting fast-talking agent Ari Gold(Jeremy Piven) -- who will apparently be fighting another agent to represent Fictional Jessica. Simpson posted on Twitter that she spent 2 days filming her guest spot, and has "the utmost respect for the entire cast and crew." What she didn't mention was that she shared a dressing room with a porn star! Sasha Grey, whose name appeared next to Simpson's on her trailer door, is a 22-year-old adult film star who crossed over into legitimate acting with the indie film The Girlfriend Experience. Grey, also playing herself, will be the next major love interest for main character Vinnie Chace (Adrian Grenier). We imagine sharing a trailer with a professional naked person might have been intimidating -- but then again, after traveling the world to meet supermodels and plastic surgery addicts, Jessica Simpson has seen it all!

The new season of Entourage premieres on June 27th, after True Blood and Hung. Other than Simpson's guest appearance, the most buzzed-about Season 7 news is Adrian Grenier's new haircut.
