Charlize Theron, 51, flaunts age-defying physique in green fringe gown as she joins Jessica Alba, Serena Williams and Sienna Miller at Airbnb.org Gala

Charlize Theron sent temperatures soaring on Wednesday when she hit the red carpet of the Airbnb.org Gala in a sizzling emerald green gown.

The 51-year-old Oscar winner’s fit figure made her look years younger than her true age as she led the stars at the event in Los Angeles.

Theron was joined at the gala by stars including Jessica Alba, Serena Williams and Sienna Miller, among many others.

Alba favored an elegant black single-shoulder gown, while Williams opted for a playful leopard-print dress and Miller looked angelic in white satin. 

The event marked Airbnb.org’s first-ever gala. Unlike its for-profit sibling company, Airbnb.org is a nonprofit that offers free emergency housing to those devastated by natural disasters, illness or other crises.

Theron’s gown featured long green fringe that nearly touched the floor and parted naturally to reveal her toned legs.

She highlighted her trim figure with a lustrous green waistband that matched the halter dress’s shimmering collar.

The actress contrasted her colorful dress with black open-toe heels decorated with enormous puff balls over her toes.

She complemented her footwear with dark nails, and she wore her blond locks tied back in a slightly messy style.

Joining Theron on the red carpet was Airbnb co-founder Brian Chesky, who looked dapper in a classic black tuxedo. 

Alba projected classical elegance in a black gown that was ruched around her midriff.

The strapless look featured a single shoulder, and she paired it with standard black pumps that elevated her stature.

The actress styled her caramel-colored hair with a middle part, and she swept back her hair to reveal her diamond-studded earrings. 

Alba posed for photos with her friend, the socialite and influencer Carlos Eric Lopez, who rocked a chic double-breasted tuxedo with a baggy fit that he dressed down by skipping the bow tie. 

Williams highlighted her muscular figure in her leopard-print dress, which was decorated with glittering silver sequins. 

The 45-year-old tennis star’s sleeveless dress featured a low-cut top and thick straps, and she paired it with pointy black heels.

Williams had long platinum-blond curls that complemented her silver-toned outfit and were swept to one side and cascaded down her shoulders.

She added a splash of color to her look with a splash of scarlet on her lips and a matching shade on her nails, and she showed off a passion for horology with a black ceramic Royal Oak from Audemars Piguet that featured a perpetual calendar and an openworked dial.

Audemars Piguet doesn’t list the retail price of the difficult-to-obtain luxury sports watch, but secondary-market listings for it and similar Royal Oaks price it between $400,000 and $600,000.

Sienna Miller’s all-white ensemble looked like the negative image of Alba’s all-black outfit.

The 44-year-old British actress was draped in a single-shoulder white satin gown with folds radiating from a knot at her hips.

The long dress dragged on the floor and completely covered up her footwear, and Miller kept her accessories minimal with diamond earrings.
