Dolly Parton reveals why she didn't want Miley Cyrus to go brunette again

• Dolly Parton "clutched her pearls" when Miley Cyrus considered going brunette.
• Cyrus said she's never seen Parton more scared than when she considered ditching her blonde locks.

Dolly Parton and Miley Cyrus are both iconic blondes. But when Cyrus considered going back to brunette, her godmother "clutched her pearls" — and convinced her not to.

Parton recently sat down with Insider to discuss her new line of Southern baked goods with Duncan Hines, and shared more about the moment with Cyrus.

Cyrus previously told "Today" host Hoda Kotb that Parton was terrified when she revealed she might dye her hair brunette before their New Year's Eve special.

"I've never seen Dolly actually scared before," Cyrus recalled. "But I told her, 'At the end of the year, I just really want to do something different. I think I'm going to dye my hair brunette.' She acted like I told her the worst news you can imagine."

"She clutched her pearls, gasped, and went back, and she goes, 'You can't do that. You are me,'" she added. "So, I will be blonde."

When Insider asked Parton about the moment, she replied: "Miley just seems like a blonde to me. She's a bombshell, period."

"I think she's absolutely beautiful," Parton added. "Of course, she has the dark stuff in her hair now. But you know Miley, she's going to be something different tomorrow. She's going to look fashionable. She's going to do what she does."

"We accept Miley as she is because I love the fact that she's brave enough to do whatever she feels like doing," Parton said.

Parton opened up to Insider about her close relationship with Cyrus, also sharing what it was like to sing "Wrecking Ball" with her goddaughter.

Cyrus has broken down in the past while performing the tune, which has become intertwined with the end of her and Liam Hemsworth's decade-long relationship.

Cyrus and Parton sang the song while hosting "Miley's New Year's Eve Party," turning it into a medley with "I Will Always Love You."

"Even when we were rehearsing, Miley was crying," Parton recalled.

"The fact that we were singing so well together stirred up our emotions very much," she said. "She would just have these tears coming down and it was so emotional."

Parton added: "I think that's one of the reasons why the song sounded so good. We both put our heart and soul into it, and both felt what we were singing — and singing about."

Parton also told Insider that she'd love for her goddaughter to play her in a biopic one day.

"I think Miley would be great," Parton said. "She's tall, but you can't really tell that in a movie."

"And she'd have to put on some weight, and get some bigger boobs," Parton added with a laugh.

But when it comes to food, Parton revealed that she won't eat anything Cyrus cooks because "it would have no taste."

"Even if she cooked me something, I'm sure I'd have to doctor it up a little for myself," Parton said. "I would have to have some bacon grease."
