Isla Fisher just updated her long layers in a major way—less than an hour before hitting the red carpet, at that. In the moments leading up to The Brothers Grimsby premiere in Hollywood last night, the star made the spontaneous decision to cut 10 inches off of her flowing mane. (And here we were thinking that two-inch trim with our stylist was daring.)

"We did it last minute before she went on the red carpet, about 40 minutes before she left," her hairstylist Adir Abergel tells People Stylewatch. "It was my idea. I came in and she was like, 'What do you want to do this time?' and I said, 'Let's do it—let's chop it off!'" And if Abergel's Instagram is any proof (see, below), they certainly had a blast during the process. Get a closer look at Fisher's new 'do, as well as more celeb hair makeovers, in our gallery.
