The Coronation Street actress, 39, took to Twitter to DENY claims she was expecting a proposal this year from personal trainer Matt.
Kym tweeted: "So....apparently @mattwjbaker we are getting married!!! funny that! I don't recall you asking me??? Best get a frock sorted (sic)."
Matt replied: "Yea, me neither kiddo... Must have been sleep talking between ourselves.... I think Argos is open... I'll pop in and grab a ring (sic)."
A source had told The Sun: "Kym and Matt are really happy together, and she has confided in pals that they are talking about getting married soon."
Kym, who plays Michelle Connor in Coronation Street, began dating Matt last year. They'd dated for a couple of months previously a few years ago.
In an interview with OK Magazine in May, Kym revealed the pair had just moved in to a new house together, saying everything as "going well" between them. "I feel happier than ever really. Matt and I are coming up to our one-year anniversary and the time's flown by.
She was previously wed to EastEnders' Jack Ryder and Hollyoaks star Jamie Lomas.
