The sour puss kitty known as Grumpy Cat is starring in her very own TV movie called Grumpy Cat's Worse Christmas Ever.

The grumpy kitty stopped by INSIDE EDITION with her owner Tabatha Bundesen.

INSIDE EDITION’s Steven Fabian asked, “Is it hard to believe that this all started with sort of an internet meme and now we have a Lifetime movie?”
 
“Absolutely! Everyday is like a ‘pinch me’ moment. I still have a hard time believing it,” she said.

Grumpy Cat's Worse Christmas Ever airs Saturday on Lifetime.
