Katy mocks Sesame Street ban

Katy Perry's been mocking her Sesame Street ban.

The star's much-hyped cameo on the show has been dropped after parents complained about the low-cut dress she was wearing.

So on 'Saturday Night Live' Katy appeared in a comedy sketch wearing a very low cut Elmo top (right) which prompted Saturday Night Live regular Amy Pohler to say "Looks like todays show is brought you by number 38 and letter double D," (a tweet posted by Russell Brand earlier in the week).

Katy was only expected to appear on the show to sing "California Gurls" and "Teenage Dream" but appeared to be game for a laugh.

However the good news is that while the cameo has been dropped from the show it is still available on YouTube and you can watch it below.
