Lea Michele" who plays uptight singer Rachel Berry in the musical TV show" is angry because the second series has focused less on her and more on other characters.
"In the beginning, she was the biggest star. But some of the biggest episodes have taken attention away from her, like the Britney Spears show, which was all about Heather Morris (Brittany). She thinks that because she has a Broadway background, this show was made for her." a source told Britain's Star magazine.
The 24-year-old actress has led some critics on her fellow co-workers including Amber Riley, Chris Colfer and Dianna Agron which lead to no good.
"It's not easy being around Lea on set. She has put several people's backs up and it's showing no sign of improving." said the source.
