About a year ago, Justin Bieber made headlines when he lopped off his famous locks in favor of a shorter do. Now, almost 12 months later, he's once again making some hair-related headlines.

So, what has Bieber done now that has everyone buzzing? Well, over the weekend, the Biebs was spotted in Los Angeles donning much darker hair than his trademark sandy blond.

When Bieber cut off his hair last year, MTV News spoke to his hairstylist, Vanessa Price, who told us about his new look, noting that it had a lot to do with Bieber's growing pains.

"We knew it was going to be a big deal," Price explained. "We knew it was going to shock fans, but we also knew it was going to be a change in terms of growing up. I think that's something that people adjust to.

"We'd been talking about it for a while and shared some ideas, but literally the day of he was adamant about the haircut. He amped himself up for it," Price continued, before describing his momentary hesitation. "The minute we started cutting, he was like, 'Wait, wait, wait.' He loves it. He's enjoying it."

The new hair color coincides with his girlfriend Selena Gomez's hairstyle changes. She recently tweeted a photo of herself sporting multi-colored highlights in her hair.

Bieber's new look may be part of a makeover for his upcoming album, Believe, slated for release later this year. He confirmed last week that Black Eyed Peas frontman will.i.am will appear on the album.

Not only does Bieber want to grow up when it comes to his look but also when it comes to his music. "The only conversation we've had about Justin's album that we're about to do is it's really important that it's the proper transition, because we've seen him [with] 'Baby,' now we're watching him grow up," Bieber's longtime vocal producer Kuk Harrell told MTV News in November. "And we can't just throw him into the adult game right away. It has to be the proper transition."
