She’s always up to something new, and earlier today (April 23) Hilary Duff was spotted promoting her new flick “Stay Cool” at the Tribeca Film Festival.

The “So Yesterday” chick looked to be having a good time as she passed the paparazzi, sporting an all-black ensemble along with a black and tan scarf and a massive handbag.
