Justin Bieber is on the ''verge'' of turning a musical ''corner''.

The 18-year-old singer is facing a challenging time as his career will have to go in a new direction now he is an adult, but production duo Da Internz - who worked with Justin on his latest album 'Believe Acoustic' - are convinced he has what it takes to become a credible adult artist.

Ernest 'Tuo' Clark said: ''I think Justin is definitely on the verge of turning a corner. A lot of young acts have that problem transitioning from being a kid to an adult and kind of when they turn into an adult things fall off, but so far, I mean.Justin, the sky's the limit. He's one of the top pop dudes in the game.''

The duo are also confident Justin will be a different artist to former teen star Justin Timberlake.

Marcos 'Kosine' Palacios added to MTV: ''It still different though, like we're in a new era, this is a new generation. His sound is different and he has a different personality, so I think I can appreciate the fact that he's really kind of creating his own lane and his own destiny with what he's doing.''
