The star refers to a number of Simpsons characters in the track, including Disco Stu, Professor Frink and Grandpa Simpson.
Lyrics in the song include: "When they're young, all little monsters learn that they are scary, ugly, stupid, shunned by cupid, overweight, and hairy.
"But every monster needs to find that secret deep inside, that transforms Dr Jekyll into sexy Mr Hyde."
