The brunette model is currently sunning herself in the States and shooting a swimwear campaign for her latest range of bikinis in collaboration with New Look.
But it doesn't appear to be all work and no play, since she has taken David along for the trip and seems to be having a great time in his company.
Well, if we had a hunky man on our arm in Miami we would be pretty happy too!
Kelly, 34, posted a handful of photos during her weekend in the sunshine on Instagram, as well as a couple with former Gladiator David.
In one of the snaps she can be seen wearing a patterned minidress and cuddled up to her rumoured beau, who is sporting a low-cut vest and denim shorts.
She captioned the picture with a series of emoticons, including one of a couple holding hands. Could she be hinting that David is indeed her new man?!
Kelly also uploaded a shot of her catching some rays and wearing a pair of red sunglasses with a black and white swimsuit. She wrote: "PoolTime". Lucky thing!
Meanwhile, David poked fun of his super muscly image by standing next to a large spray painted image of Popeye - something which Kelly was noticeably impressed by, as she posted the funny photo with a lovestruck emoticon beside it.
The couple are now rumoured to be dating since they've been inseparable for most of this year so far.
Last month, David was pictured out with Kelly in London on numerous occasions and he is even thought to have moved into the TV star's home.
Judging by these recent snaps, it's hard to deny the sparks between them!
