Miranda Kerr is preparing to celebrate her milestone 40th birthday.

But the former Victoria’s Secret model could have passed for a woman half her age on Saturday as she graced the Breakthrough Prize red carpet in Los Angeles.

Along with her husband, Snapchat billionaire Evan Spiegel, the Australian beauty exuded Old Hollywood glamor as she posed in a strapless black dress with a sweetheart neckline.

Miranda paired her form-fitting dress with a diamond necklace and matching earrings.

The founder of KORA Organics wore her dark brown locks in an elegant chignon and completed her look with bright red lipstick.

Tech entrepreneur Evan, meanwhile, looked dapper in a black suit and matching bow tie.

Miranda has previously said that she eats extremely clean foods and keeps healthy to maintain her toned figure.

The first step is healthy eating. I eat mostly organic when I can. I eat extremely healthy because when I do, I have more energy,” she said.

“I like spinach, avocado, lots of vegetables and broccoli.”

She added to E Online, “I’m about 80 percent sane, 20 percent indulgent, because I don’t believe in denying yourself anything.”

Miranda rose to fame at the age of 13 after winning the Dolly Magazine modeling contest.

She then became Australia’s first Victoria’s Secret Angel in 2007.

She now runs her own skincare company, Kora Organics.

She and Evan share two sons: Hart, four, and Myles, three. She also shares son Flynn, 12, with ex-husband Orlando Bloom.

She is very close to Orlando and his fiancé Katy Perry, with the singer previously saying their relationship dynamic was that of a “modern family.”
