John Mayer, I enjoy his music but as a person I find him absolutely pretentious.
I find Lady Gaga to be a little pretentious too sometimes, but she's such a sweetheart to her stans and fans that I never really get annoyed with her.
Taylor Swift annoys me a lot, I really think deep down she's an evil soul and an alien/robot took possession of her sometime early in the Taylor Swift era and turned her into a fake, plastic psuedo country star that says things like "Aw shucks"
People who show no humility and have no respect for their peers. 
Now i know why so many people disliking Avril!
