The model and actress fuelled rumours of an elopement by referring to David as her husband in an Instagram message posted on Friday (30 May).
She also referenced "wedding celebrations".
It all started when Kelly uploaded a selfie to Instagram showing herself and David cuddling up while on a train.
The interesting part was the accompanying caption: "Look how happy my husband looks. #Eurostar #France #WeddingCelebrations."
Kelly and David are known to be engaged so a secret wedding perhaps wouldn't be too far-fetched. But on the other hand, there are plenty of people who refer to their other half as 'husband' even when there is no ring.
Also perhaps going against a secret wedding is the fact the 'wedding celebrations' that Kelly refers to appears to be that of a friend. She linked in a pal to her Instagram post and that friend has images of herself getting bridal make-up done on her own page.
Confusing or what?!
Reveal has contacted Kelly's rep for comment.
Whether Kelly and David have married or not, plenty of fans sent their compliments on the selfie. One joked: "I would be happy too, being next to you". Another said: "David looks so happy that he's going to burst! Your hubby has beautiful teeth too."
Kelly and David became engaged in March after just twelve weeks of dating.
But while many fans were shocked at the speed of their relationship, former Gladiator David's sister Angela was not.
She previously told Reveal: "David is ready to settle down with Kelly, have a family and grow old with her. They both want kids and are both serious about their careers. I think they'll last the distance."
