Following her infamous feud with co-star Lea Michele, Naya Rivera faces not so gleeful consequences due to her irresponsible actions and unprofessional behavior.

Recently, there was a major altercation between the half-Puerto Rican actress and her rival Michele on the set of "Glee." "They're always icy to each other," a source said. "Naya is jealous that Lea is the show's main character. There is a lot of sighing and eye-rolling between them. They talk behind each other's backs -- a lot."

Another source claimed that Rivera's on-set drama was taking place all season, consequently causing her role of Santana Lopez to be written off the last two episodes of the popular musical. "Naya has had a lot of issues this season," a source close to the situation said. "She has been fighting with all of the lesser known directors but when veteran Brad [Falchuck] came back, she caused trouble with him and that's when the drastic measures were taken."

"She is not allowed on the Glee set anymore," the source continued. "Brad said he had had enough and spoke to all of the executives and the decision was made to write her off the last two shows of the season for causing drama all season."

The 27-year-old actress has even had warnings from the company before for causing troubles. "FOX sent her two notices telling her that they were planning to take legal action against her for all the time that she was missing because of her tantrums and walking off the set," the source said. "Naya promised that she would change her ways and she begged them 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 so they wrote her off the show."

"She's not even allowed back on the lot where they film," the source added. "Her Paramount pass has been revoked and the production team packed up her trailer with all of her belongings and shipped it to her house."

However, Rivera's representative denied previous claims about the "Glee" actress getting fired from the production -- "Any reports or rumors circulating that Naya Rivera was let go or fired from Glee are absolutely untrue. End of story."

In addition, Naya Rivera seemed not to be bothered at all by the latest claims as she tweeted: "SO excited to watch Glee tonight! #doowop #shirleymaclaine #fancy."
