The Coronation Street star looked happy as she posed for the cameras at David Gest Soul Night at the Palace Hotel on Sunday.
Kym and Dan became engaged earlier this month, when Dan proposed to Kim during a romantic weekend away.
It's thought the couple have been together seven months.
A source told The Mirror at the time: "Kym is the happiest and healthiest I've ever seen her and it's purely down to Dan. She can't wait to become his wife. Even though they haven't been together for very long, they both know it's completely right."
This will be the third marriage for Kym who was previously wed to EastEnders star Jack Ryder and Hollyoaks actor Jamie Lomas.
She has three children: David, 19, Emily, 17 and Polly, four.
Dan, meanwhile, was previously in a relationship with Hollyoaks actress Stephanie Waring, the mum of his daughter Lexi, four.
