This week porn star turned crossover sensation Sasha Grey decided to give back to her community by volunteering for the Read Across America program, which brings celebrities (as well as regular folks) into classrooms to encourage kids to read.

Sasha appeared at an elementary school in Compton, California, where she visited a first-grade classroom modestly dressed in jeans and a long-sleeved shirt and read a picture book to the kids.

Of course, none of the students in the class knew who Sasha was, nor did the teacher screen clips of her work, but angry parents still contacted the school's principal to express outrage that their children were allowed within 50 feet of the AVN winner.

As a result, the school is now denying she was ever there, despite photos of the visit obtained by TMZ.com (left).

We think they're just mad that she didn't participate in "Take the Fathers of a Classroom Full of Kids to Work" day.

You'll be more than kind of hard with kind-hearted porn star Sasha Grey here at MrSkin.com...and this time, it's the kids who aren't invited.
