Lady Gaga surprises her Little Monsters

In this Mastercard-associated short film/commercial, Lady Gaga fans joined a dance class - but the surprise waiting behind the mirror stole the show. These appear to be true superfans whose greatest dream is to dance with her - a wish that, in this case, comes true sooner than they ever imagined. It's a heartfelt "documentary" of a celebrity surprising her fans, staged or not. While moments like this can be genuine, I wouldn't bet my money on this one.
