Why is everybody criticizing Lea Michele?

Why is everybody criticizing Lea Michele?
I've been hearing a lot of criticism about Lea Michele. People are saying the she's a slut or something like that. I mean, she doesn't seem like that type of person. It's not like she's gone to jail like Paris Hilton or went to rehab 500000000000 times like Lindsay Lohan. She is very talented, unlike many stars. So, why is everybody criticizing her?
