He said: "If anyone believes I need rehab that's their own stupidity lol I'm 19 with 5 number one albums, 19 and I've seen the whole world.

"19 and I've accomplished more than I could've ever dreamed of, I'm 19 and it must be scary to some people to think that this is just the beginning."

The Sun reported that in an earlier post, which the singer later removed, Bieber said he was no Lindsey Lohan: "And to those comparing me to LINDSAY LOHAN look at her 2012 tax statements.”
