It’s been an up and down summer for country superstars the Dixie Chicks. First came the good news in July that Martie Maguire had given birth to her third child. And now comes the bad news — it has been confirmed that Martie’s bandmate and sister Emily Robison and her husband of nine years, country singer Charlie Robison, are divorced.

According to the San Antonio Express-News, the couple filed for divorce in January and the order was finalized yesterday at the Bexar County Courthouse in Texas.

A statement released by Charlie’s rep says that the former couple, "remain close friends and their family is the priority and will continue to be."

Documents filed with the court claim that the marriage had "become insupportable because of discord or conflict of personalities."

Charlie and Emily were married on May 1, 1999. They have three children together — Charles "Gus" Augustus, 5, and 3-year-old twins Julianna Tex and Henry Benjamin.
