Sizzle! Elizabeth Hurley defied age in a Tuesday, October 18, selfie where she modeled a tiny red two-piece that featured a cherry-red triangle top and low-waisted string tie bottoms from her own Elizabeth Hurley Beach collection. “Bikini time,” the Royals actress, 51, captioned.

Hurley, who is an Estee Lauder spokesmodel, constantly shows off her impressive physique to her more than 400,000 Instagram followers — particularly in her line, which launched in 2005.

“I decided to venture into beachwear not only because I've always been obsessed with vacation clothes, but also because it's an area where women, regardless of shape or size, can either look amazing or really get it wrong. I wanted to develop resort collections which make women feel fabulous at any age,” she said in a statement on her website.

The Viktor actress claims that her slim figure isn’t that difficult to achieve. “There’s no shortcut to being slim,” she told Woman’s Day in 2011. “You have to watch what you eat. I put myself under extra pressure because I still model my own bikinis.”

And surprisingly, she doesn’t subscribe to fancy diets or meal plans to stay in shape. "I have to be careful because I am 50," she said on The View in 2015. "I don't do all that green juice, I don't do any of that...powders, I don't really take vitamins. I try not to eat too much for dinner."
