Canadian sensation Justin Bieber has revealed his plans for the rest of 2013 and it seems that the 'Boyfriend' superstar will not be allowing himself a lot of down time. 

He took to his official Twitter page this evening and told his 40 million followers that before the end of the year he has a lot to accomplish and isn't afraid of a challenge:

"Rest of the world tour, movie, and #NEWMUSIC all coming this year! never stop working. #focused."

Earlier this month, the 'As Long As You Love Me' hitmaker confessed that he has started to channel all of his energy into working on brand new music along with 'music journals'. He also recently confessed that he is set to return to the studio very soon, much to his fans' delight. Watch footage of Bieber surprising singer Cody Simpson on a recent tour date here:
