VIDEO: Alison Pill blames topless tweet on her BlackBerry

You might know Alison Pill as Maggie on Aaron Sorkin's The Newsroom. Or maybe you kow her from Scott Pilgrim vs. the World or from her turn as Zelda Fitzgerald in Woody Allen's Midnight in Paris.

Regardless of how you know Alison Pill, you might also be aware that she sent a topless photograph of herself out to all her Twitter followers last year. Yup, really. She did that.

On Tuesday, Pill was on Conan to talk about The Newsroom when she explained exactly how that photograph came to be on the Internet forever and ever. SPOILER ALERT: It has to do with a new BlackBerry.
