Blondes Have More Fun! Kim & Khloé Kardashian Flaunt Platinum Hair As They Gear Up For A Sexy Summer — Photos

Great minds think alike! Over the weekend, both Kim and Khloé Kardashian took to Instagram to show off their fit figures and matching brightened locks.

The mom-of-four, 41, took a set of pictures in her closet while wearing a big pair of sunglasses, a black tank and ripped jeans, captioning them, "Blondie 👱🏼‍♀️✨," but her younger sister's posts were what really had social media buzzing.

The Good American founder, 37, sent pulses racing by posing in a bikini and matching shirt from her own line. She shared three snaps in total, and each of them put her impressively chiseled abs on display.

"Hottt🔥🔥😍😍😍," commented Kimora Lee Simmons, while good pal Khadijah Haqq wrote, "Goodness gracious."

The Strong Looks Better Naked author caught everyone's attention yet again when she showed off her flat stomach in a silver swim top on Monday, May 16. "Good Morning 💋," she captioned the post, in which she seems to be laying down on the ground.

While Khloé often rocks blonde tresses, her older sibling dyed her hair for the Met Gala, where she wore Marilyn Monroe's dress. The dyeing process took "14 hours straight," with her stylist Chris Appleton telling Vogue, "The hair look was simple to highlight the platinum color, giving the hair color and dress the attention. I wanted it to be iconic to Marilyn, but also iconic to Kim when she has her blonde moment."

Kardashian's dedication to embodying Monroe didn't come without sacrifice, as she confessed she had to lose weight in order to slip into the iconic frock.

"It didn't fit me. I had to lose 16 pounds down today to be able to fit this, but it was such a challenge," she explained. "It was a role. I was determined to fit into it. I don't think they believed that I was going to do it. Since I haven't eaten carbs and sugar in about three weeks, we're eating pizza and donuts at the hotel."

The Skims designer's admission didn't sit well with some, most notably, Riverdale star Lili Reinhart, who has battled an eating disorder.

"To walk on a red carpet and do an interview where you say how starving you are ... because you haven't eaten carbs in the last month ... all to fit in a f**king dress? So wrong. So f**ked on 100s of levels," said the actress. "To openly admit to starving yourself for the sake of the Met Gala. When you know very well that millions of young men and women are looking up to you and listening to your every word. The ignorance is other-wordly and disgusting."
