Canadian sensation Justin Bieber has revealed to his 31.6 million Twitter fans that he's been busy working on ideas for next year and can't wait to share them because they will come as a shock.

Writing on his social networking page earlier today (December 18), the singer explained that his 2013 events will be a surprise to everyone:

"studio today. i got an acoustic album to finish. 2013 i got some surprises. I promise you what i got planned for 2013 u r not expecting. :)"

Last week, the 'As Long As You Love Me' superstar confirmed that he is currently recording an acoustic album, much to his fans' delight, and is set to release it in January although he is yet to elaborate on his other goals for the new year.

So far, the only other confirmed news is that Bieber recently added another 30 dates to his 'Believe' tour, which are due to take place throughout June, July and August in the USA.
