R&B crooner Usher has finally opened up about his failed marriage to fellow R&B singer, Tameka Foster.

Usher claimed that the mother of his two sons didn’t see eye-to-eye with him and although things didn’t work out, he's still thankful for his time with her.

He told PEOPLE Magazine: "I appreciate the relationship for what it was. Even though it didn't work out, I'm glad we got together. I love her as the mother of my children; we just couldn't be married.

"We're two different people and we have two different goals, it just was never going to work out 100 percent.

“We had to put our issues aside and focus on raising our sons. There will never be another mother for my sons, and I'll always be their father."
