But Miley quickly hopped onto her notes app to call out double standards regarding her dating life.
It seems like the two have been getting closer ever since. Cody posted a selfie with Miley on Instagram calling her his "baby", and Miley's recent posts suggest Cody has been keeping her company while she's sick with tonsillitis.
But that's not all — people have also noticed something interesting on Cody's poetry Instagram account, Prince Neptune.
On Monday, he posted a photo of a girl (who isn't Miley — it's by photographer Sebastian Zanella)...
And the poem in the caption is all kinds of eyes emoji.
It's safe to say people in the comments think they know who the poem's about.
And yes, in case you're wondering, Miley does follow the account and therefore has probably seen the poem for herself.
Let's hope they continue to enjoy Hot Girl Fall! 🔥🍂
