A few months ago, Debby Ryan said she was single, but it looks like that may have changed! The Jessie actress posted the sweetest birthday message for her ex Josh Dun, saying that he's "the stuff of legends, fairytales, and dope action films" and that he's still her "best friend." Oh, yeah, and they're totally holding hands in the throwback photo she shared of them together.

Her split with the Twenty One Pilots drummer didn't end badly, so they could just be friends. But it's definitely suspicious that she picked a photo of them together in which they're extremely cuddly.

The couple privately broke up last fall to little fanfare, and we're so happy that they're still besties. But now we're wondering if they're a couple again. Either way, they are seriously the cutest together, whether they're just friends or in a relationship!

Do you think Debby is back with her ex? Let us know in the comments!
