Will.I.Am, who features Bieber on his new single #thatpower, believes the 'Baby' hitmaker is one of the most talented people he has ever worked with.
Bieber has been criticised for coming late for a concert in London, fighting with a photographer and his most recent bad press came after his visit to Anne Frank museum in Amsterdam.
The 19-year-old was criticised for saying he hoped the Holocaust victim would have been a fan "a Belieber".
Will.I.Am thinks it was wise of the singer to spend time in a museum instead of partying, reported the Sun.
"We are like, hey, that guy went to freaking Amsterdam and went to see Anne Frank's museum... The dude was in freaking Amsterdam. He could get sex because it's legal, he could get drugs because it's legal, and now we are making a hoopla because he said, 'I wonder if Anne Frank was a Belieber?'," he added.
