Kelly smiled contently as she donned a cute short denim playsuit teamed with tan ankle boots. The model and actress showed off her natural beauty with a make-up free face and kept her wavy locks draped over her shoulders.
She accessorised with a red chain detail strap bag and oversized red-frame sunglasses.
Meanwhile, former Gladiators star David opted for a more bold outfit, wearing an interesting palm print vest and shorts combo.
The couple, who announced their engagement in March after 12 weeks of dating, were pictured shopping for bicycles.
Meanwhile, earlier in the day, Kelly and David were photographed in more casual attire after enjoying a workout at the gym - and it's clear they only had eyes for each other!
Last month, it was rumoured that Kelly and David had already married, after she tagged him as "husband" in an Instagram post, but it was later denied.
The couple are now busy planning their wedding, and a source recently said Kelly and David are looking to exchange vows at a castle in Italy in September.
Wedding plans aside, Kelly is also hard at work on set of new TV show One Big Happy, which will air in the US on NBC after a successful pilot.
