Donna Derrico lights up extreme lingerie while celebrating turning 55 in a racy swimsuit

Baywatch veteran Donna DeRico called back to her days on the hit series as she donned a red swimsuit to her 55th birthday.

The star took to Instagram to upload a sexy shot that shows her lifting a white T-shirt to reveal ample underwear in a red swimsuit, which is what she wore on the popular show when she played a lifeguard.

In a caption to her 1.7 million followers, the bombshell wrote, “I’m posting some cupcakes for my birthday because I said I would, because I feel like it, and why not.”

The Alabama native added, “Have fun today everyone. I definitely will! I love you all!”

It comes just days after she took to the internet to respond to critics who regularly called her “lewd” sexual comments.

Donna has been celebrating her birthday all month long — on March 3 she shared a nude photo and wrote, “It’s my birthday month, so here I am in my half suit for my birthday.”

And on March 9, she uploaded another unrevealed photo and said, “It’s National Barbie Day.

It’s also still Donna DeRico’s National Birth Month. Here I am honoring both of them today sitting in a pink Barbie to let you know I’ll be posting some cupcakes on my birthday.

Fellow actress Tracy Bregman paid tribute to her friend Donna on Thursday as she shared a throwback photo of the two in bodycon dresses.

Captured on a night out, dressed fabulously, Bregman wrote along the bottom of the photo: “Whether we’re casually walking down the street lol or talking through life’s ups and downs, you’re always by my side.

Happy birthday, beautiful @donnaderrico.

D’Errico later reposted the streamed tribute to her Instagram Stories.

Last week, the star shared her frustration with the haters who called her sexy posts “salacious.”

And on Sunday, the Playboy model once again expressed her anger at trolls who portray her as insignificant.

Donna took to Instagram to share a sexy photo of herself in a hot pink lacy lingerie while at her home in Los Angeles. She was in profile as she flashed a shy look.

I clapped back in the caption as I wrote, “If this sucks, so is it with @victoriassecret.” I think that’s beautiful.

My first tiktok post and everyone is going crazy are you serious. With all the indecency out there? People kill me. I laugh. Link in bio!

In another post recently, she was wearing a sheer white swimsuit and said in the caption, “Here I am squatting again in a bathing suit.” It’s fun doing this thing called whatever I want.

Then she complimented her fans: “I love you guys so much. Thank you all for being so kind. Have a great day.

Prior to this, the blonde beauty took to Insta Stories to slam critics in the post who called her pinup shots “salacious.”

Donna shared a screenshot of the post’s title, which read: “Baywatch Donna D’Errico launches smutty TikTok account with smutty bikini videos.”

Feisty: In another post recently she wore a sheer white swimsuit and said in the caption, “Here I am squatting again in a bathing suit.” It’s fun doing this thing called whatever I want.”

Donna didn’t appreciate how she was portrayed in the article and gave the outlet a bite.

The artist defended herself and said, “Um…it’s literally one video of me in a bikini.

“clickbait is nice but I don’t appreciate it because I’m not vulgar and I don’t post or do vulgar things.”

The mother-of-two regularly directs followers to click the link in bio where there is Linktree access to her Fans Only account that reads, “She wears bikinis, makes millions.”
