Miss Piggy may be glorious in front of the camera, but her behaviour on-set is quite the opposite.

We got a whiff of the diva when we saw her rider. And that whiff became a ver-y strong smell when we shot her for an ELLE cover.

However, according to her Muppets Most Wanted co-stars, James McAvoy, Ricky Gervais and Ty Burrell, the Pig is unbearable to work with. When asked about the atmosphere on set, none of her three co-stars had anything good to say.

Want proof? We caught it all on film...

Watch James McAvoy confess to doing 'it' with Miss Piggy
