The model founder also posted a series of photos on her own Instagram account showcasing the warmer tone, captioning the carousel of images with a simple, "????????."

In the photos, Bieber opted for a classic style featuring baggy blue jeans and a plain white cropped T-shirt that highlighted her toned abs, paired with chunky gold earrings. The look helped to keep the full focus on her chestnut-colored bob as she swished it back and forth for the camera. A pop of color on her lips in the form of cherry gloss topped off the outfit.

The "cinnamon cookie butter” color is a brighter departure for Bieber, who wears her hair in a bob of varying lengths colored blonde to a more subtle dirty brown. However, it's not the first time Bieber has opted for a brighter look, having debuted a pink hairdo in 2018 as she celebrated New Year’s Day with friends on a Miami beach.

In January, Bieber debuted her new blunt bob, in a dark brown hue. Next, she followed up that bold chop with another cut two months later, taking her bob even shorter. Posting to her Instagram, she played with the chin-length hair as she smiled. Before opting for the shorter haircut, she shared that "short = more fun ??????" in another post that gave a close-up of her evolving hairstyle.
