Usher has broken silence on his failed marriage to R&B singer Tameka Foster and said the mother of his two sons could not fully see eye-to-eye with him.

Promising no ill will toward Foster, Usher was still appreciative for his time with her.

“I appreciate the relationship for what it was,” he says. “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.
