Siren Kelly Brook is making sure temperatures sky rocket in Florida.

The sexy model is stateside shooting for a new bikini campaign and has been delighting Miami crowds with her saucy photoshoots on the white sands.

Yesterday was no different as the 34-year-old splashed around in the surf in a clinging bikini. The flattering bandeau style top barely contained Kelly’s famous assets and with her hair loose around her shoulders, the former TV presenter looked naturally stunning.

And lingerie model Kelly, who is dating former Gladiator David McIntosh, took time out of her hard working schedule of posing in the glaring sunshine to take a dip with her new beau.

It appears Kelly is becoming quite the US pin up as her bikini antics – with hunky David – have been reported on American gossip site TMZ. Kelly later tweeted a series of messages of support from fans who praised her curvy frame.

Kelly also recently stripped off for what could be her sexiest photoshoot yet. Model Kelly posed in her underwear to flog her sexy smalls.

Lingerie designer Kel gives a generous expanse of boob in one of the snaps in a cheeky polka dot cami as well as proving she’s ‘legs 11’ with her perfect pins in just a slinky black top.

Kelly’s currently in Miami where she’s spending an awful lot of time with her musclebound man mountain of a boyfriend where they recently ventured into the sea for a bit of splashing fun.

Dressed in an itsy-bitsy teeny-weeny black and white striped-bikini, Kelly flaunted her ample curves as she frolicked in the sea with her new boyfriend, David McIntosh.

The gladiator, who showed off his HUGE tattooed pecs and arms, was seen lifting his girl out of the waters and admiring her impressive physique, as she giggled and splashed about.

The superfit pair looked a picture of happiness as they floated about in the Pacific Ocean.

The lovebirds were still all smiles as they made their way back up the beach and headed back to their hotel.
