MUMBAI: Country singers Blake Shelton and Miranda Lambert reportedly split because she was not ready to have children.

The couple announced on Monday that they had separated after four years of marriage and it has now been claimed that they had different ideas on when to start a family.

“He is eager to have children, but she really enjoys not being tied down. I think they both were off on what the time frame would be,” pagesix.com quoted a source as saying.

The source said that Lambert's more rigorous touring schedule kept the pair apart for long periods of time.

“They are never together, and he was wanting them to move close to being together. She really loves her career and touring. She has the ability to go and record albums when she wants and to tour,” the source added.
