We’re wishing a very happy birthday to Olivia Dunne!

A staple of the SI Swimsuit family with four consecutive photo shoots under her belt, the former Louisiana State University gymnast is celebrating her 24th birthday on Thursday, Oct. 1. To commemorate the occasion, Dunne stopped by Instagram to share a cheeky new photo carousel, quickly reminding her 5.1 million followers of her SI Swimsuit résumé.

In the cover photo of the celebratory set, the model sipped a drink, rocking a blue bikini and accessorizing with a playful “Birthday Girl” tiara. Other snapshots shared showed her fun-in-the-sun day spent by the pool in the Bahamas, including a sweet photo of her posing with her longtime boyfriend, Pittsburgh Pirates pitcher Paul Skenes.

The birthday girl’s comments were also flooded with well wishes from fans, famous friends and, of course, several members of the SI Swimsuit family!

“Happy birthday pretty girl!!!” Ellie Thumann wrote.

“I wanna be you when I grow up!!!!!!!” Katie Austin proclaimed.

“I love it,” Olivia Ponton added. “Happy birthday to the hottest girl!”

“Happiest Birthday, Livvy! ❤️,” SI Swimsuit editor-in-chief MJ Day penned, to which Dunne responded, “Love love love ya!”

So—to celebrate Dunne’s special day—we’re looking back at all four of her timeless SI Swimsuit shoots! Scroll on to see a few of our favorite snapshots through the years.
