I'm not a giant fan of guest judges on American Idol. I don't mind when musicians come in during the later rounds to mentor the contestants, but guest judges during auditions just kind of throw off the dynamic of the judging. However, recent judges like Kristen Chenoweth and Neil Patrick Harris are awesome enough that I totally don't mind them showing up. Avril Lavigne and Katy Perry? Well, that's an entirely different story.

FOX has announced that the "I Kissed a Girl" singer will be guest-judging the final two days of the Los Angeles auditions along with Lavigne, who from what I remember from 2003, is an angry Canadian. If I was asked to think of two people that I would enjoy watching less, I would be hard-pressed to come up with anyone. Wait, okay. Heidi and Spencer Pratt would be worse, but that's just a given, right?

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.
