The country artist shared a photo of his new 'do on Instagram, much to the surprise of his fans.
Keith, 46, is pictured looking down and smiling away. The American Idol judge decided to keep his fringe, but cut off large chunks of his shoulder-length mane at the back.
Keith also seems to have gone for a darker shade, toning down his blonde highlights.
The snapshot instantly gained almost 9,000 likes from his followers, but fans showed a mixed response in their comments.
"Don't cut more off are u crazy??? Grow it back pleaassseee," wrote one follower.
"I miss your long hair but you look hot," said another.
Keith teased fans the day before with another photo on Instagram of an empty barber chair surrounded by tufts of hair.
"Snow ain't the only thing falling in Nashville today!! –KU," wrote the crooner.
