Katy Perry was supposed to guest star on Sesame Street, but her boobs were too exposed. TMZ reports that 'Sesame Street' has decided not to run a clip featuring her and Elmo performing 'Hot N' Cold' in a low-cut top.

Many YouTube comments comment on the fact that Perry's boobs appear to be hanging out of her dress, in a clip aimed at kids who may not even be weaned yet.

Except, as TMZ points out, the top was actually just flesh-colored fabric—not Katy's actual boobs. Which makes you wonder why anyone would cover up boobs with something that looks exactly like boobs. Crazy Children's Television Workshop! Anyway, it's good that we don't expose children too early to Katy Perry's boobs—at least not before they can learn about them in school.
