Katy is set to appear on a special episode of The Simpsons that will air on Christmas Day.
Ironically her Simpsons cameo was taped before Sesame Street! She must really love showing off her ta-tas!
Over the weekend Katy was the guest performer on SNL and she made fun of her Sesame Street boobies fallout by wearing an Elmo low cut top. There was an entire skit dedicated to how well she's "developed" upstairs. Hilarious!
