The Judds on Ashley Judd's Memoir: 'Secrets Keep You Sick'

Naomi and Wynonna Judd are just two of the big names performing and being honored on "Girls Night Out: Superstar Women of Country," and the Grammy-winning duo get serious exclusively with ET's Nancy O'Dell about daughter/sister Ashley Judd's painful childhood past, speaking out for the first time about her new memoir.

"I think it's key for us to spend time figuring our own reality," says Naomi. "Every unhappiness is tied to a story, and we have to go back and figure out our stories. And then it's our stories that connect us."

"And the veil has been lifted," adds Wynonna. "Secrets keep you sick and families will heal once you get real."

In her new memoir All That Is Bitter & Sweet, out today, Ashley details her battle with depression as a result of growing up with molestation, loneliness and neglect.

Also honoring Loretta Lynn, Miranda Lambert, Martina McBride, Jennifer Nettles, Reba McEntire and Carrie Underwood, "Girls Night Out: Superstar Women of Country" airs April 22 on CBS.
