The new season of Entourage, which premieres on June 27, will feature celebrity guest stars from Eminem to Drew Brees.

But we think we know which famous face will receive the most attention this summer: porn star Sasha Grey will appear as herself for multiple episodes of the HBO hit. She'll star as Vince's new girlfriend.

Ceator Doug Ellin said he was inspired to cast Grey after watching her leading (clothed) role debut in Steven Soderbergh’s 2009 movie The Girlfriend Experience.

“I think Sasha’s going to have a very successful transition,” Ellin told TV Guide Magazine. “Sasha’s the biggest porn star in the world right now, and when Soderbergh casts her as the lead of his movie, I take notice."

Ellin said he would have axed the storyline if Grey had not accepted the role. She was the only adult movie star ever considered for it.

Grey does have some television experience... sort of.

She's anchored several X-rated DVD spoofs of hit shows, such as Seinfeld: A XXX Parody, Not Bewitched and Sasha Grey’s Anatomy.
