Ryan Murphy has found extreme success with the hit FOX show Glee, but the cast isn't feeling the love from the creator, according to Us Weekly.

A source from the show tells the mag:

    "Things are really bad on set. The cast talks about how much they love Ryan, but they have grown to hate him. He has bad mood swings and can be really mean."


The source adds that "Lea[Michele] is leading the charge" against Murphy. Michele's rep has denied there are problems between the actress and the show's creator.

An insider says that Lea and the 46-year-old Glee creator got into it after she said she didn't want to go on the cast's 2011 summer tour. "He asked her which of her friends she wanted him to fire," adds the insider.

Ouch! Doesn't sound too gleeful.
