Usher thinks Justin Bieber's troubles will improve his music.
The 20-year-old pop superstar has had multiple scrapes with the law in the past year, but Usher believes it is all part of his protégé's life, and will ultimately make the 'As Long As You Love Me' singer a better musician.
He explained: "Any artist has ebbs and flows in their life and career."
The teen heartthrob rose to fame via YouTube in 2007 before releasing his hit single 'Baby' in 2010, but has had a troubled time in 2014 which has seen him arrested for multiple offences, including driving under the influence, resisting arrest, vandalism and dangerous driving.
But his 36-year-old mentor Usher believes audiences are yet to hear the best that Justin - who is managed by Scooter Braun - has to offer.
He told The Guardian newspaper: "I think the story is just begun, you've not seen the best of his talent. In life, you have to go through something to get to something.
"From that the inspiration comes having something of substance to talk about; otherwise you're just considered to be fluff."
The 'Yeah!' singer - who will release his eighth studio album 'UR' in 2015 - is able to speak from experience about the young singer, because he was once given vital advice by his elders in the music industry.
Referring to what late soul legend James Brown told him, he said: "He always told me, 'If you stay ready, you ain't got to get ready.' "
On advice from the late Michael Jackson, he revealed: "[He told me] if you want to continue to be great, you've got to work hard."
