Kristen Stewart is a Cake Eater

Kristen Stewart smiles and waves to photographers as she runs some errands in Los Angeles on Tuesday afternoon (March 3).

The 18-year-old actress just returned to the States after premiering Twilight in Tokyo, Japan with co-stars Robert Pattinson and Taylor Lautner.

Kristen‘s other flick, The Cake Eaters, is being released on March 24 on DVD. The flick is a quirky, small town, ensemble drama that explores the lives of two interconnected families coming to terms with love in the face of loss.
