Alison Pill (Scott Pilgrim vs The World, The Newsroom) pulled a Hayley Williams today accidentally tweeting a topless picture of herself (NSFW photo here) to her 13,597 followers.
She quickly deleted the photo. No word on how it happened but she was probably trying to DM someone.
And here we get to see the real purpose of Twitter. The only reason it was invented. To have the technologically challenged accidentally post nude pictures of themselves.
