Selena Gomez filmed Feed The Dog in Los Angeles on Tuesday, and the 20-year-old starlet wore a pink candy striper uniform (and her gorgeous smile!) when we snapped her on set.

The movie is based on Ric Browde's novel, While I’m Dead...Feed The Dog, which follows a sixteen-year-old boy who finds himself on a wild adventure when he "ends up in the back of a limo on the road to rock 'n roll superstardom opening up for Bowie," according to a plot synopsis.

The film also stars Mary-Louise Parker, Elisabeth Shue, Heather Graham, Jason Lee and Dylan McDermott, and the characters they're set to play include "a few dead Mafia hitmen, a nymphomaniac next door, narcoleptic nuns, inept policemen, unscrupulous lawyers, buffoon reporters, huckster televangelists and greedy relatives."

Can't wait to see which one Selena plays!
