Well look at what the (grumpy) cat dragged in . . . Pharrell Williams's infamous hat ! Internet sensation Grumpy Cat looked typically unimpressed when she arrived at the MTV Movie Awards in LA on Sunday sporting the "Happy" performer's now iconic chapeau. Grumpy Cat will undoubtedly get an opportunity to rub paws with A-listers at the big award show as stars like Emma Stone , Andrew Garfield, and Cameron Diaz  are expected to make appearances. It's only fitting that Grumpy Cat can get some star sightings as another famous pet, Boo, recently got fussed over by none other than Seth Rogen .
