Taylor Swift will be a Jellicle Cat on Christmas Day!

Taylor Swift shared a picture of a cat couple days ago hinting at the big surprised we didn't see coming.

She will be starring in the popular 80's Broadway musical 'Cats' with some of today's huge acts. Jennifer Hudson, Idris Elba, James Corden, Rebel Wilson, and Taylor will take on the roles of little cats who roam the streets seeking ways to ascend to a higher side in their city.

From the costumes to the dancing and singing, we can tell this won't disappoint. Check out the full trailer below
