Sports Illustrated swimsuit model Katie Austin is celebrating five years with the brand. The fitness and wellness guru (Mom is ‘90s workout video icon Denise Austin) is the perfect fit for the job, with her flawless figure rocking one teeny bikini after another.

And she revisited some of her steamiest looks to celebrate her milestone anniversary. Her video of her favorite moments even included her partying with sports royalty.

“Grateful for my sistas and the best year YET [SI Swim]!!!!” Austin, 32, captioned her new Instagram Reel. Over the video she wrote, “When 2025 marks 5 years of being in Sports Illustrated Swimsuit and the best yet.”

In the video, she scorches in one teeny bikini after another — and parties with SI Swim icon Camille Kostek and her boyfriend Rob “Gronk” Gronkowski; Olympic rugby queen Ilona Maher; Detroit Lions quarterback Jared Goff’s wife, SI Swim model Christen Goff; and golfer Brooks Koepka’s reigning Rookie of the Year model wife, Jena Sims.

“YOU sure bring such FUN, energy and pure kindless to everyone!!!,” commented her famous mom. “Xoxoxo.”

“We had the best year,” added Kostek.
