Justin Bieber Debuts Dreadlocked Look, Asks the Question We're All Wondering -- Why?

By
Justin Bieber debuted a new look via Instagram on Sunday -- dreadlocks!
He posted two pictures to the social media platform, with one captioned simply, "Why." 

The second shot, posted at 2:30 a.m., had no caption, but he showed off both the new look and his shirtless bod in the mirror self, so who are we to argue?

Twitter users have had some hilarious reactions to the new 'do.
And some have noticed that Bieber's hair now bears an uncanny resemblance to the fingers of a famous Christmas character...
Biebs often likes to be experimental when it comes to his hair. Let's never forget this purple hair and abs combo he debuted in January. 

The "What Do U Mean" singer is slated to perform at the iHeartRadio awards show on Sunday night. Check out a preview of the lineup in the video below.
