Bieber racism: Stars support singer after second apology
Justin Bieber's manager Scooter Braun and Usher are among celebrities who've responded to the singer's recent racism controversy.
The 20-year-old has apologised twice in the last week for videos that have emerged online showing him using the n-word.
One of the clips, both of which show a younger Bieber, includes a joke about joining the Ku Klux Klan.
He said he needed to "take responsibility" for his mistakes.
He posted Bible verses on Instagram asking for forgiveness.
Earlier this week he also said sorry for another film in which he made a racist joke that he called a "childish and inexcusable mistake".
'How a man reacts to mistakes... defines him' - Scooter Braun
Scooter Braun, who is widely credited for Bieber's rise to fame having discovered him on YouTube, posted a statement on Instagram which seemingly refers to recent events surrounding the singer.
Braun also represents Ariana Grande, Carly Rae Jepsen and Cody Simpson.
'Am I in it with him? Yeah' - Usher
Meanwhile, Bieber's former mentor Usher has told Nylon Guys magazine that he will stick by the star.
He said: "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."
The 35-year-old singer added that working with Puff Daddy from a young age help his career.
"Artist development made me who I am," he said.
"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."
'It's wrong but he's a child' - Russell Brand
Russell Brand is also among the names to discuss the recent videos.
Speaking on his YouTube channel, the comedian said Bieber's age needs to be taken into account when looking at the clips, one of which is thought to have been shot in 2010.
He said: "It was ages ago when he used to have that haircut. You can't do him for stuff he [has] done when he had that haircut.
"Unless we're going to explicitly say the role of celebrities is we're going to make them really, really famous and then we're going to destroy them and rip them up in a public square with fish hooks, which, you know as long as you don't get round to me, I'm not against.
"But we might as well own up to it if that is what we're up to, otherwise just let him off.
"Of course it's wrong to say the 'N-word', but he's a child."
'He's not racist, come on' - Soulja Boy
US rapper Soulja Boy, a close friend of Justin Bieber, defended the singer during an interview on radio show Sway in the Morning.
"He's not racist, come on," he said.
"All his homies is black. You got to know he's not racist. I did a lot of stuff when I was younger 15, 16. I was wilding out too."
'They're not disrespecting us' - Wiz Khalifa
Across social networks, reactions to the videos range from anger to teen stupidity. It's also got some people talking about the n-word and its use.
US rapper Wiz Khalifa said: "They [white musicians] kind of feel when they say that, that they're connecting to us, like they're not disrespecting us.
"We give them that entitlement by making music and saying it. It's art and we give him to them and they replicate it."
