Donna D'Errico Celebrates Birthday with Red Swimsuit Photo That Nods to Her 'Baywatch' Days

D'Errico dared to bare in a racy suit for a 55th birthday Instagram post

Donna D'Errico is celebrating her birthday in red-hot style.

The Baywatch alum-turned-OnlyFans model just gave her nearly two million Instagram followers a gift for her 55th trip around the sun.

The star, who played Donna Marco in the cult-classic TV show, threw it back to her "lifeguarding" days with a picture in a nearly identical swimsuit to the one she wore in the show. However, for this photo, D'Errico styled the suit a bit more scandalously than her on-screen counterpart.

For her celebratory birthday post, D'Errico posed in the water at a beach. With palm trees as a backdrop, the star got knee-deep in the ocean with her swimsuit and Baywatch t-shirt on ... only the suit wasn't fully worn.

In the photo D'Errico took the straps from her suit down, leaving only the bottom half of her one-piece in place. In one hand, the star holds the strap that would otherwise be on her shoulder, and with the other she is holding up her white T-shirt, giving a generous flash of bare skin.

She captioned the red-hot post, "Posting some cake 🎂 on my birthday because I said I would, because I feel like it, and because why not. Have fun today, everyone. I certainly will! I love you all! ❤️❤️❤️," also adding a "#linkinbio" to promote her popular OnlyFans account where she posts even steamier content.

Fans and friends in her comments wished her a happy birthday and praised her for the post. Her Baywatch costar, Erika Elenaik, commented, "Happy Birthday 🎂 to uuuuuu!," and numerous fans left admiring words such as "Happy birthday beautiful ❤️" for the star.
