Online music publication Idolator shared a recent interview with Jesy and in it, the 25-year-old is seen gushing about her husband-to-be Jake.
She insists that the couple are "very much in love".
Jesy spoke of her wedding plans and admitted she and Jake are in "no rush" to get married.
She said: "It's funny. When my fiancé proposed to me, he'd never done it like, 'We're getting married tomorrow.' He felt like when he called me his girlfriend, it wasn't enough. He felt like it really undermined our relationship."
"He loved the fact that he can say I'm his fiancée instead of just his girlfriend and I love that. I think that's really sweet," Jesy claimed.
"We're in no rush [to get married]," she explained. "When we know, we'll know and we'll do it and it will probably be really intimate. We're very much in love and we'll do it when we feel the time is right."
Jesy's interview came just days before rumours surfaced suggesting she and Jake have now split.
Speculation began after Jesy was pictured without her engagement ring, and reports claimed the couple had a "huge row."
Jesy and Jake have not addressed the claims, and when contacted by Reveal, a rep for Jesy declined to comment.
She and Jake began dating in 2014, after meeting at Manchester Arena. The following year, on their anniversary of when they first met, Jake and Jesy returned to the venue and he proposed on stage with a little help from Ed Sheeran.
At the time, Jake gushed: "A year ago today I met her at Manchester Arena, so it was only right, with a little help from my friend, that this happened. Best day of my life."
Jesy, meanwhile, said: "I cannot believe what has just happened! The most surreal moment of my life and everyone that I love most was there to share it with us! I feel like the luckiest girl in the world rite now literally cannot stop crying! Future Mrs Roche."
