USHER was on "Ellen" yesterday . . . and Ellen brought up the obvious topic: JUSTIN BIEBER'S recent behavior.
Usher said, quote, "I think all of us in some way have humble beginnings that pan out to be incredible and we hope in his transition .
. . as friends and family who have helped him be who he is . . . that he'll continue to just mature."
He added, quote, "It's been done by many, many other celebrities. They are product of it and some come out bad, and some come out good. I don't look at it as a negative though. I look at it as a teenager. He is a teenager having to live his life in front of a camera."
