Taylor Swift and Kesha might be recording a song together—or so internet sleuths are speculating, based on admittedly scant evidence. As BuzzFeed deciphered, most of the evidence is based on a single Instagram post by Kesha:

"Making a FUCK OFF song with a casual Grammy award winning secret person [thirteen star and unicorn emojis]," the caption reads. "I got a good feeling about this one."

So apparently, fans think the 13 emojis are significant, because 13 is Taylor Swift's lucky number. Is Taylor Swift casual, though? Also, is casual a synonym for "basic?"
