The model excitedly shared the photos on her Instagram page earlier today (April 15), giving fans a glimpse of her fabulous new range for the high street brand.
In one photo, Kelly can be seen in a blue and white polka dot swimming costume.
And in another, she's wearing a red and white sailor-inspired swimsuit. Alongside the photo she wrote: "Nautical but nice."
In the final pic, Kelly shows off her curves in a blue bikini, as she flashes a big smile for the camera.
Kelly took part in the sunny photoshoot in Miami, where she also enjoyed a sunshine break with her reported fiance and personal trainer David Mackintosh.
The pair have been dating since New Year's Eve and got engaged after Kelly posted a photo of them cuddling and holding a giant 'engaged' balloon.
