Gwen Stefani [2] is welcoming the cooler months with a new haircut [3], and the look may just inspire you to do the same. The singer posted a picture on Instagram announcing the launch of her brand GXVE's [4] new Bubble Pop Electric High-Performance Lip Gloss [5] ($20). In the campaign, Stefani's lips look plump, pouty, and perfect, but her new blunt bob haircut [6] also deserves your attention.

Stefani kept her hair its signature platinum-blond color [7] and styled it in loose, shaggy waves, giving off an effortlessly chic look. The bob ended below her chin, just barely grazing the tips of her shoulders. Stefani isn't typically one to wear shorter hairstyles, and over the years, we've gotten used to the singer's playful high ponytails [8], Old Hollywood waves, and pin-straight looks. This blunt bob, however, is a welcome change for the star, and it looks like it may be catching on in Hollywood.

Celebrities like Kim Kardashian [9], Lori Harvey [10], and Lucy Hale have also been seen in the blunt cut recently, so if you're looking for your own fall hairstyle [11] update, put this look in the running.

Take a closer look at Stefani's hair below.
