Reports in today's newspapers claim the Coronation Street star has temporarily cooled things with personal trainer Dan and he's moved out of the home they share.
A source told The Mirror it was a "mutual break" that partly came because of their busy schedules and despite separating, the couple remain amicable and speak often.
"They are both very much hoping to work through what is a very difficult time for them and get their relationship back on track as soon as possible."
Dan appeared to confirm a break via Twitter but insisted their engagement was still on, by saying: "Nothing's broken off. We are having space and a break. False headlines. Please leave us alone with the horrible comments."
His Twitter picture is still an image of himself and Kym.
Another insider told the Daily Star: "They decided they just needed a bit of space but both are really keen to try and make it work and want to get back together."
Kym has not commented on the claims and her Twitter bio still reads: "Actress, singer, proud sum to David, Emily, angel Archie and little Polly. Oh… and I have the best fiancé in the world."
Back in February, the loved up couple had exchanged sweet Twitter messages on Valentine's Day, with Kym saying: "[You are] the most amazing man the world. You are everything to me and more. Love you always."
Dan had replied: "You are the love of my life, my soul mate and my best friend. Love you baby."
The former Hear'Say singer became engaged to Dan in December, with friends saying at the time they'd never seen her happier.
Kym was previously married to EastEnders actor Jack Ryder and Hollyoaks star Jamie Lomas.
