Joan Collins, 91, and Elizabeth Hurley, 59, Appear Ageless in Summer Vacation Photos

Joan Collins, 91, showed off her great looks in new photos as she enjoyed a summer vacation with none other than Elizabeth Hurley, 59.

The two women enjoyed St. Tropez in France, with Hurley's son Damian and Collins' husband Percy Gibson also on the trip. The four posed in front of some beautiful wall art, with Hurley donning a flowy white halter dress to match Collins' white off-the-shoulder dress. Next to Hurley, Damian wore dark jeans and a black long-sleeved shirt as Gibson embraced vacation vibes in a tan lightweight suit jacket and pants.

Other photos included in the update showed Collins and Gibson posing with their arms around each other, along with another snap of Gibson standing in between Hurley and Collins, smiling at the camera. "Hanging with the Hurleys, having a ha ha ha ????," Collins wrote in the caption.

Fans were sincerely stunned to see how great both Collins and Hurley looked, with appreciative comments like, "Best looking women [sic] in her 90s I’ve ever seen??," and "Elizabeth looks just like she did in the 90s! Gorgeous."

Some people couldn't help but declare their favorite, such as one who wrote, "Everyone is so beautiful....but Joan is absolutely stunning ????."

"Even the stunning Liz can’t outshine Joan ??," said another.

More fans described Hurley and Collins as looking "tanned, gorgeous and healthy," "absolutely incredible," and "truly stunning ??," while one fan even described the two women as "Benjamin Button," as if they are aging backward.

In a video Collins shared a few days earlier, the English actress shared a look at her vacation and welcomed people to her home in France where she had close friends staying with her, including the Hurleys.

"C’est si bon ?? Nothing like the Riviera in August ?? #sttropez #summer #vacation #friends," she wrote alongside the clip. Hurley and Collins have known each other for many years and have vacationed together in the past.
