Glee would not be as musical as usual as two of its stars, Lea Michele (Rachel) and Naya Rivera (Santana) are involved in a controversy which is not pleasant to the ears.

There are two different versions of the alleged fight between Lea Michele and Naya Rivera that took place on the set of Glee on Tuesday.

As of the moment, it's still unclear which actress made the dramatic exit.

Insiders tell TMZ, that Rivera and the rest of the cast reportedly became annoyed with Michele after she walked off set to deal with a personal problem and left everyone waiting to finish a scene. Sources close to Rivera she had the guts to go tell producers everyone was tired of waiting on Michele.

On the other hand, Michele's camp has an entirely different take on events, purporting that she was "totally unaware" of her co-stars being irate, and it was Rivera "who got tossed off the set." According to TMZ, there's talk that Rivera was fired, but her people deny that's the case.

In addition, the "personal matters" Lea was said to deal with was actually a scheduled Twitter chat with fans, and Naya was already upset about matters unrelated to her co-star.

According to wonderwall.com, adding another layer to the story is a blind item that made the rounds this week that many suspected involved Lea, Naya and Naya's ex-fiancé, Big Sean.

The blind item states 'It involved an actress who found text messages on her fiancé's phone that showed he was involved with her co-star'. The clues seemed to point toward "Glee." Fans will just have to wait and find out the true side of the story and it'll be interesting to see whether Rachel or Santana emerges victorious in this apparent feud.
