Failed marriage was my best mistake – Usher.

R&B star Usher has no regrets about his failed marriage to Tameka Foster, calling the relationship his “best mistake”.

The ‘Yeah’ hitmaker endured a highly-publicised and lengthy court battle with Foster following the breakdown of their two-year marriage in 2009, butUsher remains positive about the experience.

In an interview for the September issue of OMagazine, the singer describes walking down the aisle at the age of 28 his “best mistake”, adding, “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.”

Following their split, the former couple began a heated custody battle and in 2012, Usher was awarded primary custody of their two sons, UsherRaymond V, six, and Naviyd Ely, five.
