The 20-year-old 'Baby' hitmaker, who recently apologised to fans for being 'arrogant', grabbed headlines in 2014 for getting arrested on suspicion of driving under the influence and his on-and-off relationship with singer Selena Gomez.
Braun, however, said Bieber is in an amazing phase of his career and his next music will make it even better for him, reported Aceshowbiz.
"He's in such an incredible place right now, and he's excited to share where he is with the world next year. It will shock some people and make others really happy," he said.
The singer's last album was released in 2012.
