OLIVIA Dunne is giving fans a behind-the-scenes look at filming on the Baywatch reboot.

The 23-year-old appears sensational in her skin-tight Baywatch one-piece.

Dunne has shared a glimpse behind-the-scenes as filming starts on the reboot show.

She has appeared in the iconic Baywatch red swimsuit alongside her co-stars.

The former LSU gymnast has been cast as Grace in the legendary ’90s show’s reboot.

Ex-gymnast Dunne has shared an on-set selfie with Hassie Harrison, 35, on social media.

They appeared in matching all-red one-pieces as they stood on the beach for the Instagram Stories snap.

Dunne appeared winking and flashing a peace sign with her right hand.

Meanwhile, Harrison smiled as she took the photo.

“BAEWATCH,” Dunne captioned the post.

Dunne is one of several social media stars cast in the Baywatch revival.

Fellow Sports Illustrated swimsuit model Brooks Nader, 29, has also been added to the all-star lineup.

Nader was snapped alongside Dunne in a sneak peek at filming on the highly anticipated show.

Additionally, Stephen Amell, 44, has been cast as an adult Hobie Buchannon.

Dunne has previously shared an inside shot of herself reading the Baywatch script in the show’s famous red bikini on the beach.

Fans have set their expectations high for Dunne’s on-screen debut.

“THIS IS GOING TO BE SO FUN,” one fan commented on Instagram.

“This is so sick go you,” another shared.

Her appearance in the show was first announced earlier in March.

The Baywatch reboot is set to air during the 2026-27 television season.
