Usher has described his marriage as his 'best mistake'
"Most people probably think I regret it because I ended up getting divorced, but it helped me learn that sometimes I think I know more than I actually do," the 35-year-old said.

"I've never forgotten it, and I'm always telling people, 'Well, James Brown once told me…'"
