Justin has apparently gone back to his brunette roots. He debuted his look at the Los Angeles Clippers game Thursday night. His friend Kendall Jenner was lucky enough to witness it, posting a picture on Instagram showing it off.
It looks pretty good. But, we do notice it wasn't cut. Perhaps he's bringing the Bieber swoop-hair back? That would be pretty funny.
The Biebs' isn't the only one switching up his 'do these days. His ex-girlfriend Selena Gomez just did, too. See her drastic hair change, here.
Do you prefer your Bieber blonde or brunette?
