Kristen Stewart [1] isn't known for showing off her pearly whites, but the actress couldn't help but smile on Saturday. During a stroll with her pal Alicia Cargile, the actress lit up while chatting and taking in the brisk LA weather. Kristen kept it casual for the duo's day out, donning a beanie, sweatshirt, jeans, and Converse high-tops. Back in August, the 24-year-old opened up about why she doesn't smile more often in a candid interview with Elle [2], saying people might think she's a "sellout" if she started grinning while out and about.

The happy outing comes during a low-key month for the actress, who last flaunted her street style [3] while running errands in a "Tom Boy" t-shirt earlier this month. She's been wrapping up her busy year in LA after she returned from Riley Keough's bachelorette party [4] and made a sexy appearance at the Hollywood Film Awards [5] in November. Keep reading to see more of Kristen's smiley day, and be sure to take a trip down memory lane with all the times she got animated [6].
