An Australian photographer learned the hard way that when Ariana Grande gives an order, she means business. The singer reportedly walked out of a photo shoot after being shot from the wrong side.

According to News.com.au, Grande will only take pictures if her image is captured from the left side. The photographer failed to do so, so she stormed out. The 21-year-old informed those in the room that she was leaving to change outfits, but she never returned.

A rep for Grande asked the photographer to delete the photos, but he refused. As a result, the 'Problem' songstress' security team approached him as he was trying to leave the premises. They also wouldn't let him close the trunk of the car, where he stores his equipment.

There's been no word yet from Grande or her representatives about the incident.
