Star magazine reports that during the filming Ariana was difficult to work with, as a source who was there said, "She was a total nightmare. She demanded to be shot only on her left side and told the lighting crew that if they used red light, she would 'kill herself.'"
Whether or not this report is legit, we don't know, but if it's true, Ariana may need an attitude check.
The insider added that producers on the special "were saying that she is, hands down, the most difficult person they have ever had to work with."
At a recent photo shoot, an insider said, "She arrived hours late, with no explanation, and refused to do anything that the photographer asked."
The source noted, "She was acting like a crazy person. One minute she was all sweetness...then she'd storm out, only to come back two minutes later, all smiles. It was very bizarre."
