Flaunting her gymnast physique and a dazzling smile, she’s also celebrating her new role in the much-anticipated Baywatch reboot.

Olivia Dunne is joking that she’s “washed up” as she marks her 24th birthday with a celebratory swimwear post. The LSU gymnast and newbie actress updated her Instagram this week with poolside photos, showing off her athletic figure in a tiny blue bikini. Flaunting her ripped figure as she continues to make headlines for starring in the upcoming Baywatch reboot, Olivia sizzled in a teeny halterneck top and matching bottoms, posing with inflatables that shouted out her 24 years. The New Jersey native also included boyfriend Paul Skenes in her share, which earned her over 100,000 likes overnight.

Sipping an orange beverage that was likely infused with alcohol, Olivia struck a sassy pose with one hand on her hip, giving the camera a knowing look while wearing a girly crown. Flashing her cleavage and gym-honed abs, she showed off a golden tan and flaunted her muscular legs. Olivia returned with her “24” floaties in another slide, posing out of the water and holding them as she offered a cheeky, butt-baring view.

Fans also got a reminder of Olivia’s long-term romance with baseball pitcher Paul Skenes, who graciously lifted her up in one image. “Washed up at 24,” Olivia amusingly wrote.

Stunning In Her Red ‘Baywatch’ Swimsuit

Olivia Dunne was confirmed as a cast member for the Baywatch reboot earlier this year. “It’s something I’ve been passionate about for quite some time,” she told People, adding: “I was interested in doing that at LSU, but sports are your top priority when you’re a student-athlete at school; school and sports, but really gymnastics was my main focus.” Olivia is joined by female cast members Brooks Nader and Shay Mitchell in the series due for release in early 2027.

Mint-Green Minidress For ‘SI Swim’ Event

Olivia Dunne made 2025 headlines after landing a Cover Girl status with Sports Illustrated Swim. At a bash thrown by the magazine, she wowed in a shiny, mint-green minidress and heels, even flashing hints of her backside in some photos. Olivia isn’t the only celebrity SI Swim has featured.

• Megan Fox has stunned in a string bikini that doesn’t fit for SI Swim.

• And Kim Kardashian was a 2023 SI Swim girl in her tiny bikini.
