There were all kinds of fun activities for the stars backstage at Fashion Week. And one of them was brought to us by the very company which brought us the 4Nite glow in the dark flip flop and who has just released the sexy FIT sandals above for spring: Havaianas. A whole slew of sexy stars got crafty with their limited edition Mercedes Benz Fashion Week Havaiana using mini-initials, studs, and Swarovski crystals, and we have the scoop.

Jennifer Love Hewitt customized some white limited edition Havaianas with her initials and made another pair for her mom. Amanda Bynes and Michelle Trachtenberg both customized the charcoal limited edition with their initials. Cohabitators Justin Timberlake and Jessica Biel also got a pair of matching black havaianas with their initials. Guess the stars are tired of everything looking Swarovski-Bedazzled.

Check out all the new spring Havaianas styles below and here on the website -- and why not visit your local craft store and get crafty yourself? The cool kids are totally doing it.
