Everyone from Jennifer Aniston to Miley Cyrus is chopping off their hair these days, and now it looks like Demi Lovato is the latest lady to pick up the scissors.

The “Neon Lights” singer stepped out for a book signing of her new release, Staying Strong, on November 23, where she showed off a significantly shorter 'do than we’ve seen on her lately. The 21-year-old X Factor judge — who was still sporting her bright blue hair despite the different style — looked edgy and chic in a tailored Smythe blazer, velvet J Brand pants, and platform heels by Saint Laurent.

Of course, we shouldn’t expect the short, blue style to stay that way for long! “I love changing my hair a lot,” Demi told Allure back in 2012. “I think it’s fun. I used to always want to dye my hair blue and purple and pink when I was younger. But I was busy trying to make it in the industry as an actress, and it was hard to go in for auditions with blue hair. [...] You know you’ve made it when you can [finally] dye your hair blue!”

And what does Demi do to make sure her locks stay healthy in spite of all the change? “I really love deep conditioning my hair,” she says. “I use a Wella hair mask and leave it on for five minutes. I [also] wait as [many days] as I can before I need to wash my hair. Washing it a lot makes your scalp really dry.”
