Naya Rivera may have sang her last song on Glee.

According to various reports, the actress has been clashing with star Lea Michele and has been written out of the Glee Season 5 finale, which airs on May 13.

HOWEVER, Rivera's rep has shot down talk of any firing, making a short and simple statement to E! News:

"Any reports or rumors circulating that Naya Rivera was let go or fired from Glee are absolutely untrue. End of story."

Ryan Murphy has acknowledged that Glee Season 6 (already confirmed as the final go-around for this floundering comedy) will feature a time jump and a smaller regular cast, so it's very possible that there simply isn't room for Santana.

And a source acknowledges that Rivera's future on the series is unclear, regardless of whether or not she is feuding with Michele.

"We love Naya and want only the best for her," says an insider who works on the series. "Hopefully we can work it out.

Santana was originally scripted to share a number in the finale with co-stars Heather Morris and Amber Riley, but that storyline has now been altered.
