Amid news that Naya Rivera and her boyfriend Big Sean broke up and called off their engagement, reports are claiming that Naya Rivera and Lea Michele are caught in a feud, which may lead to the "Glee" actress leaving after season 5.

According to TMZ, the Naya Rivera and Lea Michele feud started when Naya became fed up with Lea's "diva antics." Things got so bad that Naya told "Glee" producers that she was annoyed with Lea's behavior. When Lea found out, she walked off set during filming of season 5.

But TMZ also reports that Lea's sources have a different story about what happened, saying that "Lea was totally unaware of any complaints about her ... and Lea and Naya weren't even shooting scenes together." They also claim that Naya was the one who got tossed off set.

Some sources even told TMZ that Naya was fired from "Glee," but her sources say these claims are just false rumors.

Speculation began earlier this year that Naya would leave "Glee" after season 5, and would not return to play Santana in season 6. Perhaps if there's drama between the two stars, this is more likely than ever to happen.

Lea told E! Online about "Glee" season 6: "It's New York now, so it's me and Chris [Colfer] and Darren [Criss] and Chord [Overstreet] and Kevin [McHale]." She left out Rivera's name.

Naya also wrote on Twitter in February: "On set with Glee shooting a very sweet Brit/Santana scene! #starttogetherendtogether"

It's been a tough year for Naya. Rivera and Big Sean's break up came as a surprise to many fans, who were looking forward to the wedding of the "Glee" star and her rapper boyfriend.

"After careful thought and much consideration, Sean has made the difficult decision to call the wedding off," Big Sean's rep said in a statement, Us Weekly reports. "The recent rumors and accusations reported by so-called or fake sources are simply untrue."

"Sean wishes Naya nothing but the best and it is still his hope that they can continue to work through their issues privately. We will not be commenting again on this matter," the statement continues.
