Wynonna Judd wasn't having any of the Lifestyles of the Rich and the Famous host's negativity after Robin said Naomi's white satin, feather-collared gown was "hideous."
Speaking with ET after the launch conference, Wynonna made it very clear that Robin had no business trashing her mother's style.
"You know what? She's my mom. If she wants to show up in spandex and a tube top, go girl!" Wynonna told ET's Nischelle Turner.
But Wynonna didn't let her frustration go unaddressed. Apparently, she made sure Robin apologized for his words.
"So I'm downstairs in my dressing room and Wynonna came in like a raging bull," Naomi recounted. "She said, 'He's coming down stairs now!' And I went, 'Why?' And she said, 'Because he's going to apologize to you!"
"He hurt your feelings," Wynonna added. "And I'm not going to let that happen. If anyone's going to hurt your feelings, it'll be me."
Wynonna and Naomi's nine-show residency at The Venetian, Girl's Night Out, kicked off Wednesday night and runs through Oct. 24.
