wynonna judd daughter disappearedIn Star magazine's upcoming issue, a report will emerge that country star Wynonna Judd's 14-year-old daughter Grace disappeared for several days.

"Wynonna has had problems with Grace," a source tells Star. "But she never expected anything like this. Grace just disappeared as she was traveling by plane -- with a stop -- back home."

The incident occurred earlier in 2011. The mag says Wynonna was "frantic" and "badly shaken."

"Grace was missing for days," the insider says. "Every second was like agony for her family. Her plane had a stopover, and that's where she apparently got off and disappeared. In many ways, she's a pretty resourceful kid -- but that didn't make anyone feel any better."
