Randy Travis and Wife Divorce

Lib and Randy Travis

One of country music's longest-lasting couples have called it quits.

After 19 years, Randy Travis, 51, and his manager/wife Elizabeth "Lib" Travis have ended their marriage."The divorce was finalized as of this morning," spokesperson Maureen O'Connor confirmed to PEOPLE on Friday.

The couple filed a petition for dissolution of marriage in Santa Fe, NM. The court papers say a "state of incompatibility exists between the two parties," the Associated Press reports.

In a statement, the rep says, "Elizabeth and Randy Travis have agreed to part ways. Elizabeth will remain Mr. Travis' personal manager. They do not intend to comment any further and ask for your respect for their privacy during this time."

The pair married in secret in 1991 after dating for more than a decade.

Elizabeth has been credited with turning around both Randy's life and career.

She saved him from a five-year prison stint for breaking into a convenience store. Convincing the judge to release him into her custody, Randy lived with Elizabeth and her then-husband.

Already unhappy in her former marriage at the time, Elizabeth has said, "Randy might have given me the courage to leave a bad situation, but Randy did not break up the marriage."

Elizabeth further guided Randy's career, with Randy once saying, "She is energetic, witty, intelligent – and very kindhearted."
