Nicole Kidman sizzles in gold Balenciaga during impromptu backyard photoshoot as she prepares to receive an AFI award

Nicole Kidman glittered in gold as she posed for an impromptu backyard photo shoot before being honored at the AFI Life Achievement Award gala.

The 56-year-old Big Little Lies star was recognized Saturday night at the American Film Institute’s Life Achievement Award gala in Los Angeles.

Ahead of the ceremony, Nicole shared a photo of herself posing in front of a backyard pool as she showed off her dramatic look in the sun.

Her sleeveless dress accentuated her figure, with a five-foot train falling behind her on the red carpet.

Kidman completed the look with a matching gold watch and rings, as well as a pair of pointy black heels.

The Australian actress was thrilled that the AFI honor was “beyond my wildest dreams” when she was announced as a recipient last weekend.

“Receiving this award fills me with overwhelming gratitude,” she wrote at the time. “To be the first Australian to be honored in this way leaves me speechless.

Kidman added: “I grew up as a suburban Sydney girl who just wanted to act; having built a career doing what I love is a blessing beyond my dreams. I thank the AFI for this wonderful honor.”

She later shared a throwback photo of herself in one of her first films, 1983’s Bush Christmas.

“This 14-year-old girl could never have predicted how many talented people she would end up working with and how many different characters she would end up playing,” she captioned the post.

“I’m so excited to celebrate with so many friends and colleagues on Saturday with the @AmericanFilmInstitue xx,” Kidman added.

Kidman was supported by several friends, including Reese Witherspoon, Naomi Watts, Joey King, Morgan Freeman and more.
