Justin Bieber's manager Scooter Braun has opened up about his fears for the 'No Brainer' singer.

Scooter, who also manages Ariana Grande and Kanye West, got real with The Red Pill Podcast about his worry that Justin's fame from a young age could end in an early death due to "crap in his system."

Take a look at Justin Bieber's sweetest moments with fiancé Hailey Baldwin...

"There was a time where I would go to sleep almost every night, when [Justin] had the money to fly away from me, and I was worried every night that I was gonna lose him," he admitted.

Scooter continued: "I thought he was going to die. I thought he was going to sleep one night and that he would have so much crap in his system that he would not wake up the next morning."

JB's manager said he even stopped him from going on tour, revealing: "He used to yell and scream at me, and he wanted to put music out, he wanted to tour, but I thought if he did that, he would die. So, I just refused."

Justin has had various run-ins with the law in the past, including in 2014 when he was arrested for a DUI while "drag racing" his Lamborghini in Miami.

Scooter adds that Justin is an: "extraordinary young man who’s been given an extraordinary life. And he used to complain, and he used to fight it and that’s when he got into a dark place, but when he accepted his responsibility and took a hard look at himself and not what everyone was doing, that’s when he owned it and he got healthy."

And now it seems the Biebs is doing better than ever.
