Fashion types will be happy to hear that Jessica Chastain has joined Instagram land. The Oscar winner announced it on her official Facebook page, albeit with a catch. She didn't post her username, just a clue: it has to do with the word maniac. 

People much smarter than us figured it out pretty quickly: You can follow her at @chastainiac. Right now she's filming Crimson Peak with director Guillermo del Toro in Toronto. Her only pic so far is from the Art Gallery of Ontario. Unfortunately, she's missed Fashion Week, where she's usually a front-row fixture, but maybe she'll treat us to some photos and videos from the Crimson Peak set. Or the Oscars!
