Alongside a photo of Carter, 30, rocking denim shorts with white lace, a Cyrus fan account commented on the pic to gush over the new rumored couple.
"Just wanted to let u know that u don't deserve all this hate from people who claim to be Miley's 'fans'!" the account wrote. "U and Miley have every right to do what ever u want! If u make Miley happy then I like u! Miley's happiness and mental health is all that matters."
After reading the kind comment, Carter liked the fan's post.
"Liam loves Miley and is crushed by all of this. But right now Miley doesn't want to answer to anyone," the source claimed. "She still feels the need to explore herself, her sexuality and her music. Miley has been working in the studio and wants to blow off steam."
When it comes to the two women, though, a source recently told ET that "no one thinks Miley and Kaitlynn are in a real relationship, they believe it's more fun on vacation."
"For Miley, she's having fun, and for Kaitlynn, it seems too coincidental that she is hooking up with a huge music star, when that's what she wants most for herself in life -- to be famous," the source said.
