The 'Beauty and a Beat' hitmaker has also hinted at a change in direction with the moniker, reported Daily Mirror.
Bieber, 19, replied to his fans on his Twitter account called Justin Bieber Army that the change is short-lived after they tweeted about it.
"For now," he said.
There is a possibility that the new name is linked to his switch to rap music. Bieber was recently spotted with rapper-producer TI in a studio.
