Are Luke Bryan, Jason Aldean, and Kelsea Ballerini Teasing a Collab?!

They've all posted pictures of their own faces in cornfields without any captions or context. Also, can you tell if this is real cornfield art or is this a computer generated image? I keep going back and forth on that. 

Keep an eye out for more artists posting similar pictures and we'll let you know as soon as we find out what it means!!
