Katy Perry Sings "Hot and Cold" on Ellen

Katy Perry performed her new single "Hot and Cold" on the Ellen show today and, well, I guess it was a decent performance if you like either Katy or her song (or both).  I, unfortunately, don’t like this song very much nor am I particularly a fan of Ms. Perry’s.  Still, it was a pretty good performance.
I loved that her band had on elf hats, though.  Didn’t really peg her for the festive type…
