Katy Perry apparently showed too much cleavage for the kiddies. The pop star recorded a segment for "Sesame Street" in which she sang a new version of her hit "Hot & Cold" with Elmo while wearing a gold bustier. But the PBS children's show said in a statement that it has decided not to air the video because of "feedback we've received." The video is, however, available on YouTube. See what you think. Too risque for the kids?
