"He got knocked down a little bit and he climbed up. You know, that sounds like Ali to me. That sounds like Martin Luther King to me.
"That sounds like a lot of the greats that have walked this earth. It even sounds a little bit like Jesus to me."
Brown was famously arrested in 2009 on a felony assault charge for assaulting then-girlfriend Rihanna. He was sentenced to five years of probation and six months community service.
In May 2013, he was involved in a hit-and-run case. Brown later turned himself into Van Nuys police and was released in just 30 minutes. The charges were eventually dropped.
Then, on 27 October, he was charged with felony assault after a physical altercation with a man at a W Hotel in Washington DC. District prosecutors have since lowered the charges to felony misdemeanour.
He is reportedly being sued by Frank Ocean's cousin, Sha'Keir Duarte, for $3 million after a claim that Brown's bodyguards attacked him in a studio car park in West Hollywood in January.
Of course, R Kelly himself is no stranger to controversy. In 2008, he was accused - but eventually found not guilty - of 14 charges of child pornography, after a 23-year-old woman, who allegedly featured in a sex video shot a decade previously, refused to testify.
In 1996, he was sued for $10 million by a 24-year-old woman who claimed he had had sex with her when she was just 15. The case was eventually settled out of court with a payment of $250,000.
He also famously married the late singer Aaliyah in 1994 when she was just 15, dedicating the track Age Ain't Nothing But A Number to her. The marriage was annulled after it came to light that Aaliyah had lied about her age.
R Kelly recently released his new album, Black Panties, which he promoted by setting up a special hotline. Calling the line gave fans the option to receive eight messages from R Kelly a month, though the content of the messages remained unclear.
