It may not have been Mother's Day when the latest episode of 'The Judds' (Sun., 9PM ET on OWN) was filmed, but it couldn't have aired on a more appropriate day. In it, Wynonna Judd brought her mother, Naomi, up on stage during a performance and had her sit nearby on a stool.

"You have been the joy and the intense challenge of my life. To have had this journey with you for 25 years, this is pretty unbelievable," Wynonna said of their lucrative career as a country music duo.

Wynonna then broke into a new song that she'd written to honor her mother. Naomi could do little more than sit there and beam, occasionally reaching over to grasp her daughter's hand.

"My greatest blessing on this earth and this journey has been with you," Wynonna told her.
