Katy Perry Sesame StreetKaty Perry is taking her talent to 'Sesame Street' to play with Elmo -- or at least that's what she thinks.

The singer shows up to play with the little red muppet, but he isn't exactly up for the fun.

Perry then breaks out into a kids version of 'Hot N Cold,' singing about how Elmo won't play dress up, although we're a little concerned with what she's wearing herself.

Her appearance on the long-running children's series is part of the show's 41st season.
