It would appear so. Though no one has seen it yet, a 'close friend' says that before her big break, Stone got freaky in a sex tape. According to Gawker, the tape is still in the hands of the person she made it with. Her friend claims that she made it before her big role in 2007's 'Superbad', staring opposite Jonah Hill and Michael Cera.

It looks like you can add Stone's name to the list of celebs with sex tapes and leaked naked pictures.
