(Cover) - EN Showbiz - Leonardo DiCaprio reportedly raised eyebrows when he turned up to a black tie dinner in jeans and a baseball cap.

The Hollywood heartthrob seemingly overlooked the formal dress code at an event hosted by de Grisogono Jewelry owner Fawaz Gruosi at the Hotel du Cap in Cannes, France, on Tuesday night. Rather than donning a smart suit and tie, Leonardo arrived at the bash in casual wear and proceeded to party with a host of famous faces.

"The actor turned heads at the black-tie dinner when he showed up for the post-dinner festivities in a baseball cap and jeans," reports the New York Daily News. "DiCaprio made a beeline for the VIP section table occupied by his friend Naomi Campbell and her beau, Vladimir Doronin."

Leonardo arrived alone at the event, but wasted no time in partying with several stunning models. The 36-year-old hunk who recently split from Bar Refaeli and has been romantically linked to Blake Lively reportedly took a shine to one group of ladies and had such a good time with them he decided to invite them to another party.

"Leo ended up choosing four hotties and whisking them to a private villa party at 4 am," the publication added. (C) Cover Media
