He continued: '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'.

Usher has since battled with his former spouse over custody of their two children, six-year-old Usher 'Cinco' Raymond V and five-year-old Naviyd Ely Raymond.

In 2012, a judge awarded the singer primary custody of the two boys.

Going through the divorce and custody experiences has resulted in some deeper wisdom for the star.

When asked about his best advice, the U Got It Bad crooner spoke about a meaningful encounter with one of funk and soul music's biggest legends.

'"If you stay ready, you ain’t gonna get ready." James Brown told me that right before we performed together at the Grammys in 2005.'

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