The country superstar and Blackstock separated months ago, but confirmed the sad news in a joint statement released on Monday (03Aug15).

The statement from her label Big MAChine Label Group reads: "Despite this being the end of their marriage, they continue to support each other. They have worked together for 35 years and will continue to do so. They have asked that you respect their privacy during this time."

A representative for the label declined to comment on whether the two are planning to divorce.

This is the MCEntire's second marriage split - she was previously wed to rancher Charlie Battles for 11 years.

MCEntire and Blackstock have one son together, while he has three children from a previous marriage, including Brandon Blackstock, who is married to pop star Kelly Clarkson.
