There's a difference between cheap, tawdry publicity stunts that are (pop) culturally significant and those that are just, well, cheap and tawdry. An example of the former is Madonna's infamous VMA performance from 2003 in which she performed and locked lips with not only Christina Aguilera, but Britney Spears as well. An example of the latter would be basically anything involving Katy Perry.if you've walked past a TV, into a retail store or gotten into a car this summer, chances are you've heard Katy Perry's single, "I Kissed a Girl." There's an even bigger chance that if you just read that sentence, "I Kissed a Girl" is now going to be stuck in your head for the rest of the day. Perry is performing that song during this year's VMA telecast on September 7th, and if you haven't already guessed, she's looking for a girl to kiss.
