A statement from Big Sean's representative on Wednesday night (9 April) suggested the rapper had been the one to cancel their wedding plans.
"After careful thought and much consideration, Sean has made the difficult decision to call the wedding off," a spokesperson told People.
"Sean wishes Naya nothing but the best and it is still his hope that they can continue to work through their issues privately."
Naya has yet to comment.
It has not been clarified yet whether that means they are still together as a couple, just not an engaged one at the moment.
Naya, who plays Santana Lopez on Glee, confirmed her engagement to Big Sean in October 2013, just hours after she flashed an engagement ring on the red carpet in LA.
Earlier this year, Naya told a magazine how Big Sean was essentially the "boy version" of her and that she knew after their first date he was the one.
The gorgeous star admitted: "[I called my mum and said] I have no idea who this guy is, but I feel like I've known him forever."
She added to Cosmpolitan Latinas: "I think he's going to be an amazing husband, and he'll make a great father someday. He's so kind to people, but he also wears the pants in our relationship, which I love."
