Teenage Dream Katy Perry Firework
appeared at the 2010 MTV VMAs on September 12, 2010.

On September 14, she returned to her old high school, where she performed a short set for the school's students.

Katy Perry performed a version of her song "Hot n Cold" with Elmo from Sesame Street, which was originally scheduled to run on the 41st-season premiere of the educational children's program on September 27, 2010. Four days before the airing, Sesame Workshop announced, "In light of the feedback we've received on the Katy Perry music video ... we have decided we will not air the segment on the television broadcast of Sesame Street, which is aimed at preschoolers. Katy Perry fans will still be able to view the video on You Tube."

The main reason was that parents complained about what appeared to be a great amount of cleavage shown by her dress. However, Katy Perry was actually wearing a flesh-colored mesh that went all the way to her neck.
