We hardly ever see her in a good mood!

Kristen Stewart caught a flight out of LAX today on her way to the Sundance Film Festival in Utah, and the actress flashed a grin as she made her way through the sea of photographers. She must be excited to screen her new movie Come Swim, which she both starred in and directed. The flick is described as a "diptych of one man’s day, half impressionist and half realist portraits.”

We wonder if K-Stew's girlfriend Stella Maxwell will join her in the mountain town? The ladies have been dating since the actress' split from singer St. Vincent, and they were most recently spotted together grabbing smoothies in LA on January 4.

On a totally unrelated note, since when does the Cafe Society star carry girlie accessories like handbags?! We couldn't help but notice her Chanel purse, and we guess that's one of the perks of being the fashion house's spokesmodel.

Rumor has it the brunette beauty and ex-boyfriend Robert Pattinson could reunite on screen for a Twilight sequel, but when shutterbugs asked her about that prospect, she didn't seem too thrilled. Watch the below video!
