Katy Perry has made a cameo appearance in an episode of the children's TV show Sesame Street.

The singer performed a special version of her hit 'Hot N' Cold' alongside Elmo, which was intended to teach viewers about opposites.

In the clip, which can be watched below, Perry can be seen chasing Elmo after he runs away when she asks him to play.

Perry filmed her appearance in March and joked at the time on Twitter that she was "in lurv" with the famous puppet.

The singer is the latest celebrity to appear on Sesame Street.

Ricky Gervais, James Blunt, Natalie Portman and First Lady Michelle Obama have all made recent cameos on the programme.
