But her rep insists she's not exiting the musical series, telling the Hollywood Reporter, "Any reports or rumors circulating that Naya Rivera was let go or fired from 'Glee' are absolutely untrue. End of story."
Reps for the show refused to comment on Rivera's future or any on-set incidents. It's unclear if she'll return for the sixth and final season.
According to Gossip Cop, Naya hasn't been officially fired, but her trailer has been emptied out and her pass onto the lot where the FOX show is filmed has been revoked.
"We love Naya and want only the best for her," a show insider tells E! News. "Hopefully we can work it out. ... We all needed a moment."
Radar Online alleges that the starlet has been throwing tantrums and storming off the set, wasting time and money.
"Naya promised that she would change her ways," maintains a spy, "and she begged [producers] to give her more chances, saying that she wouldn't cause any more drama. But they finally decided that the show couldn't go on with her disrupting production ..."
But insiders counter to the Reporter that she's merely on hiatus from the series, and any insinuations that she's been barred from the set or warned about her behavior are false.
Earlier this month, Rivera and Michele reportedly clashed on-set over "diva antics." The Daily News, however, downplays Lea's involvement in the rumored altercation, with a source explaining, "[Naya] went off. But it had nothing to do with Lea."
Still, a source recently told Us Weekly, "They're always icy to each other. ... There is a lot of sighing and eye-rolling between them."
Probably not helping tensions: a recent blind item that hinted Big Sean had cozied up to an unnamed "Glee" star.
