Confirming rumors, the Christian/pop singer and husband Gary Chapman announced their separation Wednesday after 16 years of marriage.
"They both ask for your prayers during this sad time and hope that you would respect their privacy," a statement from the couple's management company said.
No divorce papers have been filed. A split has been whispered about--in Nashville and on the Internet--for months.
Grant, 38, and Chapman, 41, wed in 1982. They have three children, ranging in age from 11 to 6.
Grant is one of contemporary Christian music's leading crossover artists. Her recording career spans back to the late 1970s, when she released her first album at age 17. She scored her biggest mainstream hit in 1991 with the catchy confection, "Baby Baby."
Chapman is a singer/songwriter who began to emerge from the long shadow of his wife's fame by signing on as host of Prime Time Country on cable's TNN in 1996.
Together, Grant and Chapman have served as something of the first couple of Christian music. He penned one of her first hits, 1979's "My Father's Eyes."
