Reports suggested the singer/actress would not be back for the show's final season later this year (14), but executives have issued a statement in a bid to quash the story.
They state, "There is no truth to the rumor Naya has been fired from the show. She remains under contract to Glee."
Meanwhile, Michele refused to comment on her alleged spat with Rivera as she arrived at the premiere of her latest film, Legends of Oz: Dorothy's Return, on Saturday (03May14).
But she was keen to praise her castmates for helping her cope in the weeks and months following her on and offscreen boyfriend Cory Monteith's overdose death last summer (13).
Michele said, "I owe so much to the cast of Glee. Loss is a horrendous thing... Going to work and knowing that I had this safety net underneath me, has gotten me to where I am right now."
Rivera's publicist denied reports suggesting her client had been fired from the show last week (ends02May14), and also lashed out at media reports suggesting the actress/singer had been dropped by label basses at Columbia.
She said, "Any rumours or statements made as fact, that Naya Rivera was fired or let go from Glee or dropped from her recording contract, are categorically false. Someone obviously has an agenda to damage Naya's good name and the media are failing at their duty to responsibly vet their sources and verify what is true and what is not."
Rivera portrays Glee's lesbian character Santana Lopez.
