When Hollywood's glamour girls are going for the red carpet "sex factor," they're all crazy about Italian designer Roberto Cavalli.
In New York, his designs caused an absolute frenzy when his "More Affordable" collection debuted at H&M stores.
Now, red-hot Roberto's latest project is designing the entire wardrobe for the upcoming Spice Girls' world tour.
Roberto told "Extra" he loves designing for the girls, as well as pop powerhouses Beyonce and Shakira.
"They have such a strong personality," said Roberto.
Pregnant beauty Halle Berry, who often wears his designs on the red carpet, calls the fashion genius "always very sexy, always on the edge of fashion."
Adds Sharon Stone, "He's a wonderful designer, and knows how to do chic and sexy at the same time."
