Former porn star Sasha Grey took her talents a less adult audience by visiting Emerson Elementary School and reading a book to students, which caused the school to receive several complaints and at first deny Grey’s visit, TMZ reported. “We have several celebrities who read to our students each year,” a spokesperson for the school told TMZ. “The actress you indicated was not present.” But photographs uncovered by the entertainment website and a tweet by the actress told a different story. “Spent the am with Read Across America Compton, reading to the sweetest 1st and 3rd grade students @ Emerson Elementary,” Grey tweeted. A spokesperson for Read Across America told ABCNews.com that Grey was not affiliated with the program. Grey responded to the backlash from her visit Friday by telling the entertainment site: “I believe education is a universal right. I committed to this program with the understanding that people would have their own opinions about what I have done, who I am and what I represent.” The ex-porn star, who made her last adult film two years ago, most recently appeared on the television series “Entourage” playing herself.

Personally I don't have a problem with it.  People are allowed to change.  You can't escape sanctimonious people, who just have to be heard though.
