Usher believes that Justin Bieber needs to "manage" his own life now that he's an adult.

The rapper has mentored the pop heartthrob since his career took off at the age of just 13, seven years ago, but he hasn't tried to stage an intervention following Justin's recent run-ins with the law and bad publicity as he insists the youngster needs to learn from his own mistakes.

"I gave every bit of advice and always told him it was up to him if he really wanted this. Now that he has it, as an adult, it's his to manage. Do I turn my head in shame based off of what I see, what I know? Nah, I don't because it's all part of life's process. Am I in it with him? Yeah," Usher said in Nylon.

Usher, 35, was mentored by Diddy from the age of 15, so he understands why it's important to have someone else in the industry looking out for you. "Artistic development made me who I am. Somebody took the time to help me find what it is that works for me as an entertainer and who I am as a music maker," he explained.
