Naya Rivera & Big Sean engagement OFF, break up & cheating RUMORS viral on Twitter: did 'jealous' rapper steal jewelry from 'Glee' ex-fiancee after split? #Trifling

"Glee" starlet Naya Rivera and rapper Big Sean are no longer engaged.

The couple officially announced that they were dating back in Apirl 2013 - they initially met via Twitter. They later announced their engagement in October.

Apparently, Rivera and the Hall of Fame crooner are "holding off on wedding plans" in order to work through some personal issues. A rep for the Detroit emcee told Gossip Cop on Wednesday (April 9), "After careful thought and much consideration, Sean has made the difficult decision to call the wedding off." 

The statement continues:

"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 26-year-old singer and 27-year-old actress have yet to comment on the break-up rumors. But Rivera did post some incriminating tweets about Big Sean allegedly stealing some expensive jewelry from her home after the couple's split...

In a tweet that has since been deleted, Rivera claims:

@NayaRiverasNews: "@bigsean stealing rolexes from a lady's house now. Maybe cuz I'm on Glee and making more money or something. '#trifling.'"

Rumors also suggest that the rapper cheated on his stunning fiancee, which is why the break-up is currently turning nasty.

But reps for Big Sean deny all claims. Sources tell TMZ:

...The cheating rumors are 100% false... Sean actually made the decision to call off the wedding weeks ago. We're told he thought Naya was too controlling and too jealous of the women he worked with and met on tour. 

Wow.

And the hip-hop crooner allegedly did NOT jack Rivera's Rolex - because the luxury watch actually belongs to him. He let his ex-fiancee occasionally wear it, but that's it. He bought it when he first became successful.

Crazy stuff - stay tuned as more details develop!
