On Wednesday, a new rumor surfaced online accusing rapper Big Sean of once again cheating on his ex-fiancee' Naya Rivera with a mystery cast member of her hit TV show "Glee."

Blind Gossip released the following report:

“It is hurtful when your fiancé cheats on you. It is even more hurtful when it’s with someone you know. This pretty television Actress found hookup text messages between her Fiance… and one of her television colleagues! She screamed at The Fiancé about why – of all the people in the world – why would he f*ck around with one of her colleagues? The Fiance couldn’t even deny it. The evidence was right there on his phone.”

In the past, Big Sean had rapped about his ex, “My new girl on Glee and shit, probably making more money than me and sh*t,” in Drake’s hit single “All Me”. The once happy couple met through social media and frequently displayed their fondness of each other via Instagram and Twitter.

There are no details as to who this mystery woman is, but luckily there are only so many female cast mates we can potentially link to the artist.

According to XXL Mag, after calling off their engagement last week (April 10), Rivera accused Sean of stealing her Rolex, which reports say actually belonged to Sean who loaned it to [Rivera] while they were together.

The cheating allegations are also said to be the reason why Rivera is parting ways with the popular singing show.
