Selena Gomez may try her hand at a serious role in the thriller 'Getaway,' but it wasn't all seriousness on set. The 'Stars Dance' singer couldn't contain her laughter in a behind-the-scenes video!

In the clip, two crew members bicker about the backseat of the car they're riding in, with one of the crew members complaining that it's wet. Gomez calls him a "germaphobe" and there's talk of a "monkey baby." Seriously. We don't blame Gomez for giggling, "If this doesn't make the behind-the-scenes [footage] I'm going to kill someone!"
