I was tempted to just put up these pictures without an explanation and let you think Hilary Duff spends her free time dancing on rooftops, but she's actually on set filming her new movie Greta. And while I have no idea what the movie is about, judging from these shots (and these sunglasses) you can be sure this movie will be chock full of wild hijinks. And, if they're still shooting for that Academy Award, alien lesbians.
