The Coronation Street star got engaged to boyfriend Dan Hooper last week, following a seven-month whirlwind romance, and the pair are already planning their big day.
It will be Kym's third wedding – following marriages to former EastEnders star Jack Ryder, 33, and former Hollyoaks star Jamie Lomas, 38 – but that isn't holding Kym back.
A source said: "Kym doesn't care what people say about this being her third marriage, she knows Dan's 'The One'.
Kym, 38, has three children – David, 18, Emilie, 15, and Polly, four – while Dan, 31, has four-year-old daughter Lexi from his previous relationship with Hollyoaks' Stephanie Waring.
The source said: "Kym she can't wait to unite their two families. It doesn't bother her at all that this will be marriage number three.
"It took Elizabeth Taylor a few times to get it right and Kym thinks it's the same for all the best girls."
