Billie Eilish debuted a new hair transformation just before the Grammys. The “Birds of a Feather” singer got a major chop, opting for an edgy and trendy hairstyle that you might even be tempted to try out yourself after seeing hers.

Eilish first gave a sneak peak of the new haircut on Instagram. She posted a mirror selfie to her story. It seems like the purpose of the upload was to show off her merch, but we couldn’t help but notice her new hairstyle. The singer posed with her head tilted to the side, letting her brand new short layers frame her face like a hime cut or step mullet. However, upon closer inspection, rather than just cropping the front money pieces, it seemed like she opted for a short layer that went all around her head like a jellyfish cut.



She went on to debut the new look at the FireAid benefit concert in California. To go with the edgier style, she opted for a baggy white button-up shirt, an oversized striped polo, and a big polka dot tie.

Whether or not Eilish will give the new look its red carpet debut at the Grammys 2025 tonight is anyone’s guess, but we wouldn’t be surprised if we saw more jellyfish cuts popping up all around these days. With Eilish’s influence, we might just think about scheduling a trip to the salon. If you’re feeling inspired like us, here are some things you should know about a jellyfish cut.

What is a jellyfish cut?

ICYMI: Jellyfish cuts have been on the rise for the past year, becoming one of the hottest hair trends of 2024 per Pinterest Predicts. It’s still a longer cut thanks to the layers underneath, but the top layers of the hair are cropped like a bob. So, it's short and round on top and long on the bottom, resembling a jellyfish. In a TikTok, hair stylist Brad Mondo described it as “a very artsy haircut” that’s “hard to pull off.” It seems like Eilish took the risk, and it might just help the style maintain its momentum in 2025.

How to do a jellyfish cut?

The best way to get a jellyfish cut is to consult your hair stylist. They’ll help you decide the best lengths and bangs to go with, whether that’s long curtain bangs like Eilish or micro bangs like Zendaya. And, according to Glamour, the upkeep can be quite simple because the bottom layers can grow out as much as you like. The top layer just needs some cleaning up from time to time.

How to style a jellyfish cut?

The jellyfish cut can be styled in many different ways. Curly, wavy, and straight hair all work for this look. You can also opt for as much or as little volume as you’d like. To go super flat, opt for a hair straightener. If you’re opting for a very round top bob layer though, you might want to make sure you have a blowout device or brush and keep some dry shampoo, texturizing spray, or root boost in your beauty closet.
