Gomez did a few screen tests last week, but Tuesday was her first day of shooting and it took place at a gas station in Atlanta.

A source told eonline.com that Gomez stayed indoors to keep warm until it was time to do her scenes.

Selena also posted a photo with her co-stars Paul Rudd and Craig Roberts and wrote: "Hi. This is the Fundamentals of Caregiving. Watch us in a theater soon. Well, let us shoot, edit, hopefully not re-shoot, then release it."
