Perry revealed in an interview with Radio 1 that "Hot N Cold" would in fact be the follow up single to her number one hit "I Kissed a Girl" in the United Kingdom and Australia. Katy Perry made the live television premiere performance of "Hot N Cold" on NBC's Today show outdoor concert series on August 29. Blender magazine calls the track a "spunky, climate-controlled kiss-off." The song went for ads on the North-American radios on September 9 and remained the song with one of the biggest bullets of the entire media base for weeks.
