We can see what Demi Lovato was going for here, and we're pleased to say she achieved it. We can't fault her look and her dress. In fact, the dress is beautiful. It may not be the best choice of prop - and her partner for the evening isn't up to her standards - but Ms. Lovato will have been turning heads on prom night from the moment she walked through the door.
Having your photo taken in front of a luxury car is a statement that says 'I'm a big deal.' She must have been getting practice in for all the glamorous photoshoots that she knew were going to come in her future. Not the pose that her partner has struck - he's got his arms out wide in a shrug, as if he can't believe he gets to take her out for the evening! There's nothing wrong with 'faking it until you make it' so long as you make it in the end. Nobody can deny Lovato has done precisely that.
