Justin Bieber Cuts His Hair -- The PHOTOS

The very fabric of the universe was altered today ... Justin Bieber got a haircut ... and it was unveiled on TMZ Live!

The Biebs underwent a little snip-snip today while on the set of a music video for a song he did with Rascal Flatts -- that's Gary from the group (above) having a little fun with the scissors. (Ed.'s note: Kids, don't play with scissors

On TMZ Live yesterday, Justin said the actual cutting was done by his regular hairdresser Vanessa. He said he was a little nervous about the cut, but he "wanted to change it up" and he thought the cut was "kind of a mature look."

They grow up so fast. 

  UPDATE:  The hair that was cut from Justin's head has been collected and will be doled out to a few organizations for charity.  TMZ is getting a lock and we're going to use it to raise money for some animal charities.
