Blondes have more fun together. 

After all, Kendell Jenner couldn't help but invite her fellow newly blonde bombshell Emma Chamberlain out together after they both underwent the major hair transformation.

In the YouTuber's Instagram post debuting her newly lightened locks Sept. 15, the Kardashians star commented, "wait let's hangout blondie."

While showing off her new 'do, Emma also shared insight into her hair journey and what inspired her to achieve her blonde bob.

"I've felt boring for a while now," she said in her YouTube video. "Not like boring on the inside, of course, but boring on the outside. When I look in the mirror, nothing excites me and I'm kind of sick of it. I think it's time for a haircut."

But she ended up going for more than just a haircut. And even though her hair has been damaged by bleach in the past, the color seemed to be calling her.

"You would think by now I would've learned my lesson, Emma," the 23-year-old noted. "We probably shouldn't do anything crazy to our hair anymore. We've had a lot of traumatic events. I don't know. Maybe it's just time to let it grow out and get really healthy again. Well, unfortunately, sometimes I can get really excited about an idea to a point where I don't critically think about whether it's a good idea or not, and that might very well be happening with this haircut idea."

After spending most of the video contemplating her new look, with the approval of her family and stylist, she went for a short platinum bob. She concluded the video with a paper on the wall that read, "Blondes have more fun," which she noted earlier in the video was something she learned when she first made the change in 2020 before dyeing it a dark brown due to damage.

Kendall, meanwhile, swapped out her dark brown tresses for a more golden-blonde hue just a few days earlier, which she revealed at New York Fashion Week. Alongside a series of photos taken in front of the New York City skyline, she simply captioned the Sept. 11 Instagram post, "blonded."

And it turns out the look took more than a few hours, according to celebrity colorist Jenna Perry, who helped her with the transformation.

"It took me two days to take her this gorgeous shade of golden blonde," Jenna told Vogue earlier this month. "She is really inspired by the '90s and Caroline Bessette-Kennedy right now."
