"Ariana is a real friend," she went on. "There's never been a time where I've asked her to do something that was important to me and she didn't come through, and the same thing me with her."
While Miley was, of course, only playfully flirting with her friend, she has been very open about her sexuality for years.
In October 2016, she opened up to Variety about being pansexual, saying: "I always hated the word 'bisexual,' because that's even putting me in a box. I don't ever think about someone being a boy or someone being a girl."
Asked when she first identified as pansexual, Miley explained: "I think when I figured out what it was. I went to the LGBTQ center here in LA, and I started hearing these stories. I saw one human in particular who didn’t identify as male or female. Looking at them, they were both: beautiful and sexy and tough but vulnerable and feminine but masculine."
"And I related to that person more than I related to anyone in my life," she went on. "Even though I may seem very different, people may not see me as neutral as I feel. But I feel very neutral. I think that was the first gender-neutral person I’d ever met. Once I understood my gender more, which was unassigned, then I understood my sexuality more. I was like, 'Oh — that’s why I don’t feel straight and I don’t feel gay. It’s because I’m not.'"
However, earlier in her "Used to Be Young" series, Miley identified as bisexual.
