Sports Illustrated covergirl 2012 Kate Upton is positively sizzling in a new campaign for Beach Bunny swimwear!

She's only 19, but she's already a supermodel and Kate Upton certainly knows how to keep the spotlight of the fashion world trained on her!

The curvy American beauty has shot an amazing new campaign for Beach Bunny swimwear alongside designing a signature line for the brand that carries her name.

In this latest 'Bronze' collection, Kate ups the ante in a series of sexy swimsuits "inspired by the golden sandy beaches and crystal clear water of the Mediterranean". Take a look!

We start off with this super-hot pink sliding triangle top and matching bottom, with stone and gold chain detailing.

Next we have this white halter monokini with plunging neckline and tie-up tassels at the side.

Kate shows off her pert derriere in this cheeky shot, wearing a paisley print bikini.

Her next two-piece reflects the beauty of a deep blue sea -- and her legendary figure!

The supermodel gives us classic black with textured gold rings in this next photograph, along with her trademark smouldering look.

For those who like a zigzag print, Kate shows exactly how to carry it off -- get a load of this ruffle-trimmed stunner.

Her appeal continues to ruffle feathers with this push-up bikini featuring an orange lace overlay.

And finally, we see her in a corset-style balconet top with criss-cross tie-up at the back.
