Justin Bieber is taking his performance "to the next level" in his new string of shows.

The pop superstar is currently preparing to hit the road on his upcoming Believe concert tour, which kicks off September 29.

Justin has been rehearsing extensively and is committed to putting on a phenomenal show for fans.

"I don't want to be just another teen heartthrob," Justin told USA Today.

"I know some people are waiting for me to fail, thinking, 'Oh, his time's up.' Well, I like being the underdog, and this tour is my chance to take things to the next level. I've never put in more hours preparing, because I want [the tour] to be perfect. I want it to be an event."

Justin is hoping that his dedication to artistic growth will appeal to people who haven't heard his music.

The star will put in the work to impress new audiences.

"I love it when I hear, 'I didn't used to like JB,' because that means I'm getting through to new people," Justin said.

"I'm rehearsing every day. I want people to see this tour and go, 'Wow, that was something I didn't expect.' "
