Most of the celebrities I hate come from the music world... and offhand I can only think of Mary-Kate and Ashley Olsen. I've disliked them since they were on Full House, and they're just sucky actresses. They make the same movie over and over again, just changing the name and the settings, and seeing their products everywhere sickens me. Most especially because, while I'm 21, they look way way older than me. It's gross.
