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.

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.
Sarah Jessica Parker
Sarah Jessica Parker parted ways with her typical hairstyle to sport the Y2K aesthetic at Max Original’s “And Just Like That…” Season Three photocall in New York City. In the past, the “Sex and the City” star and her beloved character Carrie Bradshaw routinely donned middle parts; however, the actress noticeably switched it up for the event in May.
Tisha Campbell
Tisha Campbell styled her cherry cola hair in a side part for the BET Awards 2025 held at the Peacock Theater on June 9. This was the first time in a while that the “Martin” actress chose to split her hair on the side instead of the middle.
Cara Delevingne
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
Singer and actress Reneé Rapp arrived at the 2025 American Music Awards in late May with a chic blond ‘do akin to popular 1950s beauty aesthetics. She also opted for a side part, curling her front layers away from her face to keep the hair out of her eyes.
Simone Ashley
At “The Mastermind” red carpet in Cannes, Simone Ashley took a page from the early 2000s beauty playbook. Her hair, often styled by Peter Lux, was parted on her left side, with bountiful curls falling down her back.
Lily-Rose Depp
Lily-Rose Depp added a touch of attitude to her overall look at the 97th annual Oscars, parting her hair on the right side of her face. Her long, barrel curls glided down her cheek, shielding the outer corner of her eye.
Aja Naomi King
For “The History of Sound” red carpet at the 78th annual Cannes Film Festival in May, Aja Naomi King slicked her dark tresses to the side, pushing the other half of her hair behind her shoulder. The “How to Get Away With Murder” actress often works with hair artist Geo Brian. However, Stéphane Lancien was behind this look.
Addison Rae
Addison Rae has been tapping into her inner Britney as of late, sporting the early 2000s hairstyle in her music videos, street looks, and red carpet appearances. She started the trend at the Hot 99.5’s iHeartRadio Jingle Ball in December, curling her dirty blond hair over the right side of her face.
