Justin Bieber Cuts His Famous Hair

Star unveils new 'do on 'That Should Be Me' video set.

After months of teasing that he might cut his famous hair, Justin Bieber debuted a shorter 'do Monday.

TMZ got the lowdown from the pop sensation on his new look. Photos of the cropped cut — courtesy of his hair stylist, Vanessa — appeared on the website Monday. In one photo, Bieber is with Gary LeVox, lead singer of Rascal Flatts, on the set of the video for their duet, "That Should Be Me," from Bieber's Never Say Never - The Remixes.

Biebs explained that he "wanted to change it up" and that he thought the cut was "kind of a mature look." He will turn 17 next month, so perhaps the new 'do is a step in an older direction for the teen star.

So, what will happen to the remains of his famous former swoop? Well, TMZ reports the clippings will be given to charity to raise money for various causes, including animal rights.

In December, Bieber foreshadowed the perfect timing for a haircut, saying, "I think after my movie, I might cut my hair a little shorter." It was a sentiment he first shared with Barbara Walters.

Last year, Bieber's pal and maybe girlfriend, Selena Gomez, admitted that she wanted to shear off his locks. "Everybody wants to cut his hair. I want to cut his hair!" she revealed in October. "You're with him and you have, like, a 45-second conversation and it's like, [he's flicking his hair the entire time], and I'm like, 'Why are you doing that?!' "
