Country legend Dolly Parton has only ever been honest in the past—she wasn't afraid to call out her scummy boss and she rightfully called out that bitch Jolene. So, there's no reason not to trust her when she says that ex-fiancés Miley Cyrus and actor Liam Hemsworth are back together. Also, Parton is Cyrus's godmother, so she would know. Parton admits that Cyrus's and Hemsworth's relationship is back on in this interview from Entertainment Tonight, starting at 1:18:
"Yeah, she's great, she's a talent," Parton says about her goddaughter. "She's deep, she's smart. She's sensitive. She's gone through a lot, she's been put through a lot. She's put herself through a lot." (She's put herself through getting rightfully criticized for making fun of Jodie Sweetin, that's for sure).
The interviewer then asked Parton if she was happy that Cyrus and Hemsworth had resumed their romance, to which Parton replied, "Yes, I do. I was really happy to hear that they had gotten back together." So, there you have it. She's as honest about celebrity relationships as she is about her plastic surgery.
