The newspaper reports that Kym was overheard proudly telling staff in a travel agents she and Jack, who have been going out together for six months, were planning to get hitched next year.
She'd popped into the travel shop for Disneyland Paris brochures and decided to ask about castles for wedding-hire while she was there.
Rumours of Kym's engagement to Jack, who plays EastEnder's Jamie Mitchell, came out two weeks ago.
The couple are said to be "besotted" with each other and can't stand to be apart.
Awww, how sweet!
