Hollywood's famous fashionistas turned up the heat at Leonardo DiCaprio's 2nd annual auction gala in Saint-Tropez, France on Wednesday night.
Kate Hudson dazzled in an embellished, sheer Julien Macdonald gown, which she paired with black platform heels and a matching Tyler Alexandra clutch. The actress posed for pictures with Nina Dobrev, who looked gorgeous in a white Reem Acra gown with CSARITE by Erica Courtney drop earrings.
Michelle Rodriguez was also in attendance at the star-studded soiree, leaving little to the imagination in a completely sheer gown with black underwear underneath.
As for the host, he looked as dapper as he could with that grizzly beard in a blue suit. The actor's girlfriend, model Kelly Rohrbach, stunned as well -- see her sexy dress in the gallery above!
The actor's foundation, which the star set up in 1998, supports more than 70 projects across the globe.
"Over the past year, we have expanded our conservation, public advocacy and direct-support programming to help preserve and protect wildlife in nearly every corner of our planet, but there is still much work to be done," he said in a statement. "Today, only 12 percent of natural wild lands receive formal protection, and that number is drastically smaller for our oceans, which stands at less than 2 percent."
