Kelly, who has appeared on the big screen in the likes of Piranha 3D, School For Seduction and Keith Lemon: The Movie, recently revealed she had postponed her wedding with David until later this year.
The couple got engaged after a whirlwind romance and now plan to tie the knot after David leaves the CBB house.
Sh recently told Star magazine: ‘We were going to get married next month, but we had to postpone because of my TV show and his work commitments. We don’t want to rush it.’
