Katy Perry goes to a more sanitary and child-friendly environment of Sesame Street, and sings about the difference between hot and cold!

Perry dons a veil and golden gown (after wearing Cupcakes bra in California Gurls, this is a welcome break from outrageousness!) to play with Sesame Street's Elmo singing her hit "Hot N'Cold" to teach the viewers of the beloved children show the difference between hot and cold. The song was of course, sanitized and made more child-friendly as well.

In the video, Perry invites Elmo to play dress up, but Elmo runs away. The pop star begins singing, "You want to play so I wore dress up clothes..." to the tune of the pop star's hit song.

"[The two] sing about opposites in "Hot and Cold" a spoof of [Perry's] hit song as part of Sesame Street's 41st season," according to Sesame Street YouTube account. So far, the video is getting favorable feedback with one user saying, "I wish sesame street was this cool when I was a kid."
