Lady Gaga. I totally agree with what [MENTION=8858]Flannen[/MENTION] said. She definitely makes a mockery of herself and everything she stands for.
Also, agreeing with others: Will Ferrell. I can't stand to watch anything with him in it. It's just not funny.
Usually, I absolutely hate Steve Carrell about as much as Will Ferrell. They are kind of the same person. But, I did just see Crazy, Stupid, Love yesterday and I was really impressed with Steve for once. He made me want to cry a few times, but he still was his annoying self at parts, but other than that I saw a really different side of him.
Angelina Jolie. Okay, I love/hate her. I can see how people think she's beautiful but I see a lot of ugly, too. She also REALLY annoys me when she's in a movie, but I really enjoyed her performance in Changling.
Paris Hilton and Nicole Richie. Just, why? They've never done anything with their lives. They've each had a few failed TV shows, but that was even AFTER they were already famous?!?
Miley Cyrus is one of the most untalented people I have ever seen/heard/whatever. I'm pretty sure all of her baby fans grew up and realized how terrible she is, or their parents forbade them to have anything to do with her...so WHY is she still making movies/CDs???? I don't get it.
Kristen Stewart. We all know why. I won't even explain. Just btw, she always looks stoned.
Kirsten Dunst is one of the worst actresses in Hollywood, IMO. I just don't get it. She's not even pretty...soo....?
Oh jeez, and just SO many more.
