Jason Aldean, Kelsea Ballerini and Luke Bryan are cooking something up. What? We don’t know . . . yet.

Over the course of the last 24 hours, all three artists have posted individual photos on Instagram—without captions—that depict their likenesses created on landscapes.

Some folks have theorized that Jason and Kelsea may be joining Luke on his six-date Farm Tour (Sept. 27–29 and Oct. 4–6), but Kelsea is occupied as part of Keith Urban’s Graffiti U Tour each of the six dates of Farm Tour, and Jason has existing performances listed on his tour schedule that coincide with dates on Luke’s Farm Tour.

Check out the Instagram photos below, and we’ll keep you posted when we hear something.
