The 'Boyfriend' singer revealed that he has been hard at work preparing for the live shows, which will focus on displaying his skills as a dancer and all-round performer.
"I mean there's a lot of fun stuff," Bieber teased in an interview with MTV News.
"I've been really hard at work in the studio, in the dance studio, just kind of like figuring out what I want to do as far as choreography and whatnot. I think the tour's going to be really special. We got a lot of surprises."
Bieber also expressed his thanks to fans for making his 'Boyfriend' video a record-breaker for most views in one day on YouTube earlier this month.
"It's crazy," he said. "Hopefully it just keeps getting more views and more views. My fans are amazing. I'm very blessed."
