Stop the presses! Justin Bieber has a new haircut!

The Biebs caused hysteria among thousands of his hair-adoring fans last Friday at a New York City Barnes & Noble when he showed up with a shorter hairdo to promote his new memoir "Justin Bieber: First Step 2 Forever."

Not only did Bieber ditch the long eye-grazing bangs, but it looked as though his signature side-swept flip was toned down, too.

We told you this was big news.

What caused this teen idol to change his famous feathery locks? We don't know, but we suspect this young hearthrob may be outgrowing his "Baby" ways.

During his performance at the American Music Awards last weekend, Bieber's voice reportedly cracked midway through his rendition of "Pray."

Yikes! Next thing you know he'll be sprouting chest hair out his teenage T-shirts (with a flip, of course).

Now that he's toned it down a bit, will the guy in your life try a Bieber cut?

We know one NFL player who did!
