Country music legend Naomi Judd knows she wasn't the picture-perfect mom to daughters Ashley and Wynonna -- but that doesn't mean she's curled up with Ashley's shocking, headline-grabbing memoir All That Is Bitter and Sweet.

"I will probably get around to reading it, because as a mom, I certainly want to honor her reality," Naomi, 65, says in the new Us Weekly of her actress daughter's book, which alleges a childhood of "trauma, abandonment, addiction and shame."

"I was horrible," Naomi has said. "I didn't know any better."

Older sister Wynonna, 46, admits to Us that her sister's allegations -- a constant flow of pot in the house, sexual abuse at the hands of a neighbor and more -- certainly made things awkward. Reading the manuscript, Wynonna tells Us, put her in "an unbearable place between two women that I really love."

Also awkward: Naomi and Wynonna are in the midst of promoting a brand-new OWN reality show. One source tells Us that the singing duo are "furious that Ashley came out with this right when they were relaunching their career with this show."

Their rep counters this claim, while an Ashley insider adds that the book's publication date was slated prior to the show premiere.
