She's in town to film her new movie Still Alice, alongside Kate Bosworth, Alec Baldwin, and Julianne Moore. Judging from that tremendous grin slapped across her face, she couldn't care less that a.) it's freakin' FRIGID in the Big Apple today and b.) photogs are stalking her every move. She actually looks deliriously happy!

Sipping on a green juice, crunching on an apple, and bundled up in two shirts, a signature black denim jacket, red pants, sneakers (obvs), and dark sunglasses, KStew couldn't have looked like she was more in her element. I'm guessing she's thrilled to be not only back on a movie set, but working with other super-talented stars.

The film, which is about a psychologist who discovers she's suffering from an early onset of Alzheimer's disease, seems like it may even be one to rack up some awards down the road. That said, why WOULDN'T Kristen be thrilled?

Sure, some Robsten fans may be bummed this is a sign she's moving on and her ex -- currently shooting his own new film Life in Toronto -- is the furthest thing from her mind. But hey, you never know! Distance may be the thing that makes their hearts grow fonder.

What do you think KStew is so happy about?
