The 'What Do You Mean?' singer revealed his makeover on America's Today show this morning, where he performed to thousands of fans in New York City.
When he asked the crowd if they liked the hair, the response was insane screaming. We think that is a yes!
As for whether blondes have more fun, he told the show's hosts: "I can have fun either way!"
Justin's hair reminds us of when Kim Kardashian West shocked the world by ditching her dark locks for a bright blonde 'do at Paris Fashion Week in February. And TOWIE favourite Chloe Sims has also been sporting platinum tresses lately.
The Canadian popstar is on the comeback trail after being away from the music scene for some time. His last album dropped three years ago. "I feel amazing," he said today. "It's been awesome."
Justin's new single 'What Do You Mean?' is currently number one in the US, which means he's broken the Guinness World Record for the youngest male artist to debut at number one on the Billboard Hot 100. Not bad for a 21 year old!
