No, you probably haven't heard of her – but she's worth paying attention to. Thylane Blondeau is the French model and social media sensation who's been dubbed the "World's Most Beautiful Girl.

The 18-year-old's most recent Instagram update has been getting noticed by fans – while Thylane posed in a Calvin Klein bra, her post didn't come with the promotional agenda seen from the American fashion label's celeb spokespersons. That's best left to Kendall Jenner, whose holiday Calvin Klein bra basically made Instagram sweat.

Thylane posed for her snap in selfie mode and shot from the waist up. There was no fancy bathroom, no marble counter, and definitely no glam squad.

The brunette was rocking a white Calvin Klein sports bra as she flashed hints of side-boob and her taut midriff, although fans were likely glued to Blondeau's side-eye as she glanced sideways and showcased her plump pout.

Sass? Bucketloads. Bedhair? Just about. Thylane's small arm tattoo was also visible. Lingerie shots aren't too frequent on Thylane's Instagram, but the star's 3.3 million followers got their underwear moment with this pic.

The comments section to Thylane's post pretty much showered her with love and endless gushing.

"So beautiful," one fan wrote.

"Bombe," another said.

"Omggg" saw one fan lose it slightly.

Thylane's profile is on the rise. The model recently added another award to her name, although let's face it, being the "World's Most Beautiful Girl" is hard to top. October saw Blondeau win "Model of the Year" as she attended a Cosmopolitan event in Spain. Thylane took to Instagram to mark her achievement, although the award made headlines independently of Blondeau's update.

Thylane may be beautiful, but this girl is modest AF. When Frivolette interviewed Thylane, it asked her who she thought the most beautiful girl in the world is.

"Not exactly myself!" Thylane replied.

While Blondeau may not come with fame on Gigi Hadid or Kaia Gerber's level, she has walked the runway for major luxury brands including Dolce & Gabbana and Chanel.

“Dolce & Gabbana was wonderful – beautiful show and clothes and it was really well organized. They have been so kind to me. There are no words to describe the dinner; the venue was incredible and I had a really nice time with the guests,” she told W Magazine about her time modeling for the Italian brand.

Thylane may not rub shoulders with Hollywood stars, but she's got her eye on them. When interviewed by Frivolette, Thylane was asked who she thinks inspires fashion's latest trends. Blondeau was quick to mention a very famous set of siblings.

"Bella and Gigi Hadid - these are my sources of fashion inspiration. And I'm looking for my style. Rather, I'm seventeen and I'm trying to find my own style. I'll launch my own brand in September and you'll see," she said at the time.

True to her words, Thylane has launched her own Heaven May clothing brand.
