Miss Piggy, when viewed in the midst of the Muppet gang would commonly be labeled either the Leading Lady or, more often, the Diva. And this is because our cultural definition of Diva tends to lean toward “woman with outrageous performing chops who is sometimes unreasonably demanding and self-aware of her talent.” It’s a label that is both complimentary and also often backhanded; sure, you’re amazing, but could you tone it down a notch?
Which is why it’s so amusing the true muppet diva is easily Piggy’s leading man.
