Naya Rivera is allegedly furious about Lea Michele's "diva antics".
The actress apparently stormed off the 'Glee' set after getting into a row with the musical show's producers over leading lady Lea's behaviour.
Sources have told TMZ the newly-single star who has just split from rapper Big Sean was left fuming when Michele reportedly made the rest of the cast wait to shoot a scene as she dealt with personal matters.
The website has been hit with claims from both actress' rival camps that the other one was kicked off the set, with Naya's people telling them Lea left in a huff, while a Lea source insists Naya was the one who stormed off.
They also maintain that Lea - whose boyfriend and on-screen love interest Cory Monteith tragically passed away last year - was unaware of any complaints about her, and say the girls weren't even shooting together that day.
Naya, who plays sexy lesbian Santana on the hit show, has had a rough month after calling time on her relationship with Big Sean, accusing her ex of taking an expensive Rolex watch from her house because he is jealous of her success.
In a tweet which has now been removed, she wrote: "@BigSean stealing rolexes from a lady's house now. Maybe cuz I'm on Glee and making more money or something. #triflin' (sic)".
