Porn actress Sasha Grey - winner of the 2010 AVN award for best anal scene - was invited to read to first graders at an L.A. elementary school last week. The school attempted a cover up after parents became outraged.

Grey read to young students at Emerson Elementary School in Compton on November 2, participating in the Read Across America program. Sasha tweeted about the experience, calling the students the "sweetest ever". Parents, upon learning of Grey's visit to the school, contacted the PTA in anger. The PTA then contacted the school's principal.

Here's the dumb part - the school is flatly denying that Grey was ever there! A rep for the school said, "We have several celebrities who read to our students each year. The actress you have indicated was not present."

Photos obtained by TMZ prove otherwise.
