Beyond Skin, a U.K.-based vegan footwear company, provided Kurylenko's shoes, which were comprised of Dinamica, a faux suede made entirely of recycled polyester from plastic bottles and polyurethane fibers. Beyond Skin partnered with People for the Ethical Treatment of Animals (PETA) to start selling the metallic-trimmed evening shoe on March 3.

Twilight star Kellan Lutz wore a textured black eco-tux with cerulean accents by New Zealand-based H Brothers designer Jomnarn Dul. H Brothers created a limited edition line of eco-tuxes each made of up to 25 recycled plastic bottles from an eco-fabric known as Repreve. It's a part of a partnership with EKOCYCLE, a joint venture from musician/eco-tech enthusiast will.i.am and the Coca-Cola Company to help brands make sustainable products from post-consumer recycled materials.

Oscars nominee Lupita Nyong'o talks natural beauty

This year's Oscar it girl Lupita Nyong'o talked about discovering her natural beauty at a recent Essence video shoot.

The 31-year-old actress is nominated for her supporting role as Patsey in 12 Years A Slave. Born in Mexico and raised in Kenya, Nyong'o earned her award-winning role a few weeks shy of graduating from the Yale School of Drama.

On her natural hair:

"At the age of 19, I just got really fed up of always going to the salon, and it taking so much effort to look presentable before you leave the house," she said. "I just one day decided to cut it off. And I cut it all off."

On her skin:

"I don't wear makeup when I'm not working on the red carpet," she said, "except for a night out here and there."

Hollywood environmentalists Orlando Bloom, Ed Begley Jr., and Dylan McDermott helped host the zero-waste party, where guests feasted on a gourmet plant-based dinner by Akasha, a Culver City-based restaurant known for using locally sourced, sustainable ingredients. Event sponsor Cadillac also brought its newest plug-in ELR electric hybrid coupe to the event.

Vegan musician Moby and electronica duo The Crystal Method performed at the party while eco-friendly singer Michelle Branch modeled a conflict-free, lab-grown diamond ring by eco-jewelry company Gemesis, which sold at the event for $12,000.
