Kristen Stewart's 21st birthday included oysters and chocolate cake, a serenade from beau Robert Pattinson and a brand-new motorcycle gifted from the "Twilight" gang, so we hope the actress can top last year's festivities today, on her 22nd birthday.
While K-Stew has been criticized for her less than spirited red-carpet demeanor, perhaps the prospects of her upcoming projects -- "Breaking Dawn: Part 2" and "Snow White and the Huntsman" -- will cause her to crack a few smiles in the coming months.
In honor of Kristen's big day, we've rounded up 22 of her most, um, memorable poses.
