Big Sean and Naya Rivera made headlines back in October by announcing their engagement after only six months of dating. Now, the couple does it again by calling off their anticipated wedding -- with the split turned quite nasty.

The Glee actress took Twitter on Wednesday to accuse the "Beware" rapper of stealing things from her house. "@bigsean stealing Rolexes from a lady's house now," she wrote. "Maybe cuz I'm on Glee and making more money or something. #triflin." She then deleted the tweet.

However, the sources claimed that the Rolex watch actually belonged to the "My Last" rapper, who gave it to Rivera to just borrow, definitely not to keep.

In addition, the 27-year-old actress reportedly ended the engagement after discovering that her former fiancé cheated on her. While Big Sean did not respond to the tweet or the allegations in it, his representative instead said that it was the 26-year-old rapper's decision to call off the wedding and denied recent reports that he cheated on her.

"After careful thought and much consideration, Sean has made the difficult decision to call the wedding off," the rep said. "The recent rumors and accusations reported by so called or fake sources are simply untrue. Sean did not cheat on Naya and the allegations are 100% fake and untrue."

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