BRIDGERTON star Nicola Coughlan may be 37, but she's youthful enough to pass as a 19-year-old on her hit show.
Fans have been stunned by the actress, who stars as Penelope in the third season of the Netflix series.
They gushed about her youthful appearance on X, formerly Twitter, after the first four episodes of the season premiered on May 16.
"Ain't no way Nicola Coughlan is 37... she looks 20," wrote one viewer.
"Nicola Coughlan is 37, and she looks like she is in her 20s, could also be mistaken as [a] teen," seconded another.

But the secret to her ageless skin is no longer a secret.
In a Vogue video, Coughlan broke down the steps in her skincare and makeup routine.
The actress revealed that a $9.90 drugstore anti-aging serum is a crucial part of her regimen.
"I have really really thirsty skin," she said as she applied the budget-friendly product.
The Ordinary's Hyaluronic Acid 2% + B5 serum is offered in three different sizes.
A 30-milliliter bottle of the serum costs $9.90, while the 60- and 120-milliliter versions retail for $17.50 and $31.50, respectively.
Coughlan explained that one step she makes sure to never skip is moisturizing her neck.
Her boss advised her to incorporate the skincare technique into her beauty regimen.
"My boss was like, 'You need to start using eye cream, and you need to start moisturizing your neck,'" she said.

"And I was like, 'Okay, girl,' and I started it then, but I was an anomaly among my friends that I did that."
A trick she was taught is to apply the cream gently under the eyes with a specific finger without using too much pressure.
"They also told me that you should only put it on with your ring finger," she explained.
Another critical step that was a must-have, she added, is sunscreen.
Coughlan explained that avoiding the sun for a large part of her life has been the key to her youthfulness.
"I think people are sometimes surprised that I am like an old crone," she joked.
"It's quite nice.
"Being broke in my twenties was one of the greatest things for my skin.
"My friends were going on sun holidays, and I was like, 'I'm going on zero holidays 'cause I have no money,'" she said with a laugh.
"It's not worth the suntan, it's not."
