This seems kind of old to me but it was just put out yesterday. The short hair n Katy's make-up is a hint on this Sesame Street video.
Check out this version of "Hot N Cold" with Katy Perry and Elmo. I am still digging her last CD over "Teenage Dream" but maybe it will grow on me.
What do you think of Katy n Elmo's duet?-Dr.FB
