Canadian superstar Justin Bieber has revealed that the new projects he has been working on will shock the world because it's nothing people would ever predict from him. 

Writing on his official Twitter page earlier tonight (May 9), the 'As Long As You Love Me' sensation admitted that what he's doing at the moment is 'incredible' and teased that people will definitely be surprised:

"Been working on some incredible stuff and will share with you soon. No one sees this coming. Always push yourself to be great."

Bieber confirmed that he is collaborating with songstress Ariana Grande earlier this week by sharing a snapshot of them together in the studio, and Grande confessed that the song they're recording together is something Bieber wrote himself:

"Im excited about it … I’m just very excited. Justin wrote it and he brought the idea to me. And I was really excited to hear it and I’m excited to work with him. I’ve  wanted to work with him for a while. And I know it’s something our fan have been begging for for years now.”
