Sasha Grey wasn’t the first porn star to go mainstream but we’re a little surprised to see her play the lead role in Steven Soderbergh’s The Girlfriend Experience.

And now, the 21-year-old actress billed as “The Dirtiest Girl in the World,” is also the subject of a six-page photospread in Rolling Stone magazine’s latest issue.

Writer Vanessa Grigoriadis labels Grey as “the smartest person she’s ever met in the [porn] industry”

From RS magazine:

While most porn actresses would jump at the chance to get naked on the Howard Stern Show, Sasha wants to appear on the shock jock’s program with a Palestinian flag wrapped around her breasts to confront the man she believes is a closet racist.

Well, if you have never seen a Sasha Grey porn flick, she is seriously hardcore.
