Kim Kardashian
No one can ever say that the reality star isn't willing to commit to a bit.
In order to fit into one of Marilyn Monroe's most iconic gowns for the 2022 Met Gala, Kardashian adopted a strict no-carbs and no-sugar diet to lose 16 pounds in three weeks.
"It was such a challenge," Kardashian, who was accompanied by boyfriend Pete Davidson, told Vogue correspondent and BFF LaLa Anthony. "It was like a role. I was determined to fit."
The 41-year-old added that she also would wear a sauna suit two times a day and run on the treadmill, adding, "I didn't starve myself, but I was so strict."
To complete her Marilyn makeover, Kardashian dyed her signature dark tresses platinum blonde.
Kendall Jenner
Her older sister wasn't the only member of the Kardashian-Jenner crew to use the Met Gala as an excuse to switch up their look as the model debuted bleached eyebrows when she hit the carpet on May 2.
The 26-year-old, who recently returned to her natural brunette hair color after spending several weeks as a redhead, dyed her dark brows platinum blonde, a stark contrast to her all-black Prada ensemble.
Emma Chamberlain
The YouTube star is finding out if blondes have more fun.
For her second time at the Met Gala, Chamberlain was ready to switch things up, walking the iconic steps with a platinum bob hairstyle.
"I was in the salon yesterday for 7 hours and it was very worth it," the 20-year-old told LIVE from E! "I love being blonde. I thought it would really compliment this look."
Elizabeth Olsen
Wanda got bangs!
The Marvel star debuted her new fringe while promoting Dr. Strange in the Multiverse of Madness, with hairstylist Clayton Hawkins posting the first photo of her fresh chop on Instagram April 30. "Witchy Things," Hawkins captioned another snap posted several days later.
The 33-year-old's wispy pieces complement her blunt bob, which she first debuted at the Emmys in September of last year.
Iris Apatow
Gen-Z is channeling Old Hollywood.
The Bubble actress showed off a glam new hairstyle on April 21, rocking extensions which turned her usual bold bob into a soft, medium-length look. Hairstylist Clayton Hawkins posted a series of Instagram photos featuring Apatow's soft curls on the set of her Flaunt magazine photo shoot.
Back in February, the 19-year-old changed up her look by trading in her natural blonde locks for a sleek black chin-length 'do.
Lily James
The blonde bombshell is gone.
Ready for a change after portraying Pamela Anderson on the Hulu series Pam & Tommy, James showed off a much darker 'do as she attended 2022 Prince's Trust Gala in New York City on April 28.
The 33-year-old, who was previously sporting a light brunette shade, also showed off her new near-black hair color when she attended the Met Gala four days later.
