The Biebs Is Going Through Puberty!

And now he can’t sing his hit Baby in its original key!

Justin Bieber‘s voice is cracking and naturally it’s affecting his singing! He says:

“It cracks. Like every teenage boy, I’m dealing with it and I have the best vocal coach in the world. Some of the notes I hit on ‘Baby’ I can’t hit anymore. We have to lower the key when I sing live.”

We hope his mom sat him down to “talk”!!
