PICS: Jessica Hart's sexy swimwear campaign!

The Sports Illustrated beauty has posed for a series of sizzling shots wearing the latest swimwear from Calzedonia.

She's famous for her bikini bod, having showed it off in the prestigious Sports Illustrated Swimsuit Issue and on catwalks around the world.

And now 27-year-old Australian stunner Jessica Hart is Italian brand Calzedonia's latest muse, modelling their latest colourful line of beachwear.

Here's a look at her in various key pieces from the latest collection, starting with this deep pink two-piece featuring a crocheted overlay.

Next we see her in a double image, wearing both a colourblock string bikini and a yellow-black strapless.

It's time for tie and dye with this grey and pink-accented crossbody top and retro high-waisted bottoms.

The blonde bombshell strikes a balancing pose that highlights her toned figure and colourblock swimwear.

A hint of sparkle adds glamour to this hot pink bandeau and matching tie-up briefs.

Things are twice as nice once again as Jessica dons an incredible blue monokini, captured from two different angles.

A hot red number sports rouched detailing and high-waisted briefs once again.

Sunny yellow beach shorts add a pop of colour to this pleated blue bikini.

It's time for crocheted appeal once more as Jessica sprawls out in the sand wearing deep blue.

It's time to mix and match as she heats things up in this green-meets-monochrome striped set.

Its deep coral hue is a winning factor when it comes to this plunging maillot.

And finally, we see Jessica flash her shapely gams in a bright neon bikini with polka-dotted trim.
