JUSTIN BIEBER
I'm So Damn Successful ...
Not a Loser Like Lindsay

Justin Bieber has just become hateable -- he's just gone on a rant trashing people in financial straits as losers ... aka Lindsay Lohan.

Bieber's tirade was posted on Instagram ... where he touted how great he is ... "It must be scary to some people to think that this is just the beginning [for me]. I know my talent level ..."

Justin then delivered the douchiest comment since Brandon Davis' rant against Lindsay. Justin says, "... to those comparing me to Lindsay Lohan look at her 2012 tax statements ;)"

Translation -- Lindsay's a loser because she doesn't have any money and he does so he's better than her.

Justin goes on to say he doesn't think he deserves negative press and pooh-poohs stories claiming he's going to rehab.

BTW ... Bieber just deleted his rant.
