Lea Michele and Naya Rivera hate each other!

Yowser! We thought the Glee cast was perky all-singing all-dancing buddies…but apparently not.

In fact, a source on set claims tensions between Lea Michele and Naya Rivera are so bad, they are openly clawing at each other.

It comes after the pair had a showdown earlier this month, with Lea, 27, storming off set when Naya complained she was acting like a diva.

A source told Us Weekly at the time that Naya, also 27, was getting frustrated as Lea, the show’s lead, kept taking personal calls, stalling production.

“They talk behind each other’s backs a lot,” the insider told Page Six. “They hate each other.”

It’s said to stem from Naya’s jealous that her rival plays the lead character. Now it’s not the first time this month her envy has caused her problems.

Sources say her engagement to rapper Big Sean was called off due to her jealous rages. Hmm, time to control the green eyed monster?
