Vroom vroom. 

“Baywatch” star Donna D’errico posed for a sultry Instagram shoot Monday in sheer red lingerie that perfectly matched her sports car’s interior.

“Nothing, just sitting in a car,” D’Errico, 55, quipped in the caption as she struck a pose in the Ferrari.

The mom of two urged her followers to head to the link in her bio – which goes to her popular OnlyFans account – to “see more.” 

In the social media video, D’Errico wears a transparent bra top with matching high-waisted underwear, tan platform sandals and a crystal choker necklace while lounging in the driver’s seat. 

“Car? Where??” a fan joked.

“I call shot gun [sic],” another quipped.

“How do you get hotter as you get older?!?!?” a third asked in disbelief.

In March, the former Playboy centerfold celebrated her 55th birthday by nodding to her “Baywatch” days in a similar red one-piece.

She gave the throwback an even sexier twist by pulling down her swimsuit and wearing a teeny white tank on top. 

In March, the Alabama-born actress joked about launching a swimwear line “for women over 50,” after sharing an Instagram Reel in an itty-bitty bikini. 

“Follow me for more AARP tips,” the bombshell joked.

D’Errico isn’t afraid of clapping back when trolls come for her scantily-clad social media posts. 

Last year, she famously fired back at critics who said she was “too old to wear a bikini” after she posed in an American flag-inspired two-piece for Fourth of July.

“Let me tell you something that might surprise you. I can actually wear and do literally whatever I want,” D’Errico wrote, posing in — what else? — another skimpy suit.

She’s certainly kept her word ever since.
