Leonardo Dicaprio's girlfriend, model Bar Refaeli is collaborating with the Hurley design team to create the perfect little black bikini. Refaeli announced her debut as a designer this morning on Fox & Friends, decked out in Hurley attire, naturally.

Refaeli, who was just on the cover of Sports Illustrated's 2009 Swimsuit Edition, says she's always been searching for the perfect black bikini -- until now! "Hurley's clothes and swimwear have a sexy and effortless look and feel, so when you wear it, you feel confident. I wanted to capture that with my version of the Little Black Bikini, and I am really proud of the final result."

A portion of the proceeds from the LBB will go to Boarding for Breast Cancer, a non-profit that seeks to educate young people about breast cancer.

The Hurley Little Black Bikini by Bar Refaeli will be available for $120 at Hurley.com and select retailers starting May 1st -- this Friday!
