Scarlett Johansson has officially joined the side part fan club.

The 40-year-old actress arrived at the world premiere of her upcoming film, “Jurassic World Rebirth,” in London on Tuesday night, donning the Y2K hairstyle much of the beauty world hoped had been put to bed years ago. Johansson, who plays Zora Bennett in the Gareth Edwards movie, posed for pictures alongside her costar Jonathan Bailey, with her dirty blond tresses brushed over the right side of her head.

Johansson also sported a side part for the movie’s photocall in London on Monday night, channeling old Hollywood with wide roller curls and a bold red lip.

In the early 2000s, a side part on the red carpet would’ve been considered mainstream, but by the end of the 2010s, the slicked aesthetic was practically extinct. Enter the era of the middle part. Many members of Gen Z, even some who’d been fans of the hairstyle, began openly revolting against the side part (picture them with hair tools like pitchforks) on TikTok, encouraging even Millennials, who would have previously never thought to stray from the style, to divide their hair in the middle.

Yet, now we seem to be on the precipice of a modern side part revival, as many A-listers, including Johansson and Sarah Jessica Parker, revert back to the controversial hairdo. Twenty-four-year-old Addison Rae has gone in the opposite direction, too, opting to style her dyed blond locks on one side of her head as she steps into the spotlight as a rising pop star.

Here, WWD takes a look at a few of the other celebrities fronting the return of the side part, from Parker to Rae.

For the “La Venue De L’avenir” red-carpet at the 78th annual Cannes Film Festival, Cara Delevingne stuck to her signature style — blond curls parted on the right side of her head. Delevingne, 32, is one of the few stars who hasn’t ditched the side part amid the criticisms. In fact, the model prefers to keep her hair firmly tucked to one side, whether it’s for a casual stroll around Los Angeles or a runway moment.

Reneé Rapp
