Kelly, 34, announced her engagement to former Gladiator David last month via her Instagram, posting a picture of the couple holding a balloon bearing the word 'Engaged'.
They had been together on-and-off for just 12 weeks when David, 27, popped the question, having first met Kelly on New Year's Eve at her London bar, Steam & Rye.

Speaking to Now magazine about their initial introduction, David said: "I got chatting to her but I didn't think it was going to go anywhere. Kelly's a nice girl, I like her company. She's a great person and the best thing about it was we just clicked, so I've been spending a lot of time with her."
