Justin Bieber's brother was born on November 20, 2009.. I do not know how big he is.. but what kind of a question is that anyways? he's three days old for crying out loud!
Yes, he is 16 and has started to go through puberty! If you search Google images for Justin Bieber under arms there is a picture of him in a pool with his arms raised. You can really notice it there!!
