Hailey Bieber debuted a new bob haircut.

New year, new ‘do.

On Saturday, Hailey Bieber showed off her new bob cut to her more than 11 million TikTok followers.

“oops 🔪👩🏼‍🍳💇🏼‍♀️,” she captioned the video, which has been liked more than 286,000 times.

The clip begins with the model, 26, showing off her blue sneakers and then panning the camera to her backyard. She then flips the video, showing off her new blunt bob as she rocks a pair of shades and a black leather University of Miami jacket.

Bieber’s big chop prompted fans to share how influential her style was in the comments section of her post.

“Hailey cuts her hair short, now everyone will cut their hair short 👀🔥,” wrote one fan, while another added, “Hailey’s about to have all the girlies chopping off their hair.”

“So now I have to cut my hair,” commented a third social media user.

“Now all the tiktok girlies are about to have this haircut in the next 5-7 business days,” added another TikToker.

The Rhode Beauty founder has been known to set a few trends over the years.

Last summer, the wife of Justin Bieber’s “glazed donut” nails were going viral on social media — even catching the attention of Vanessa Hudgens.

She first debuted the frosted mani — which was created by LA-based nail artist Zola Ganzorigt — at the 2022 Met Gala to match her silky white Saint Laurent gown.

Bieber later updated her trendy nails to adapt to the season change from summer to fall. The beauty guru swapped out her original pearlescent white coat for a rich brown color that gave the same shimmer.

“I know we’re tired of my constant color switch up but … the chocolate glazed donut nails are really hitting for me for fall,” she captioned her September TikTok video, showing off her new manicure.
