Flawless Sports Illustrated swimsuit issue model Renee Herbert flaunts her chiseled core in a tiny string bikini while swimming outside in a dream locale.

The twin — she and sister Elisha were the first twins to be featured in the iconic magazine in almost 50 years — is home in her native Australia.

“The serenity of nature sounds and slot machines,” Renee captioned her Instagram share. The 14-image post does indeed have a pic of the model sitting at a slot machine. But most of the photos show the swimwear model in a bikini or the stunning landscapes Down Under. One video shows the twin navigating rocks and streaming water barefoot, and several pics reveal her artsy side via snapshots of her painting and the activity’s set-up.

Fellow SI Swim model Penny Lane — a nature lover herself — left two heart eye emojis in the comments.

In fact, most of the comments section was filled with the same emoji.

Renee and Elisha, 26, made their SI Swim debut in the 2025 issue, sending them to snowy Switzerland. The magazine deemed the result a “showgirl meets ski-chalet fantasy” in their feature article, posted to Sports Illustrated Swimsuit with a full photo gallery  on October 11.
