paparazzi
Interesting song and video for sure. I had to look up the lyrics to see what she was talking about. At first, I thought my fears were correct: that she was making a song about being chased by paparazzi, which is egotistical of her to do on her debut album, but I get what it is talking about now. The premise of the song is that a character is chasing a star and obsessed with him/her. Really, it may be called "stalker," but the theme of calling paparzzi selfish and intrusive has been a common theme from the earliest songs about them (thinking this is strongly reflected in "Paparazzi" by Xhibit)
So, I don't think that she is demonstrating that she is taking herself too seriously in this video. More that she is ripping on the extents that people will go to get on TV, a'la the kissing between Britney and Madonna, and Marilyn Manson, and perhaps lesbian porn.
