This has truly been the summer of incredible collaborations. Just when we thought our hearts were already fit to explode from exciting partnerships, Cody Simpson shared a photo of himself in a studio with 5 Seconds of Summer's Ashton Irwin. Oh. Em. Gee.

We're not sure what the Aussies are doing together, but they must be up to something! In the pic they're settled behind their instruments and breaking out their rock star poses. There's an acoustic guitar and hang loose hand for Cody, and a piano and rock on hand for Ashton. Cody captioned the pic: "Mixin different styles with my mate #surfrock."

Surf rock? We're not entirely sure what that would sound like, or what a Simpson-5SOS collab would sound like, but we're already totally here for it.

While waiting for more details on what they might be working on, we can set our sights on the possible acoustic album Cody recently recorded with Justin Bieber. There's also little to nothing publicly known about what they've dubbed their "special project," but again, we are already dying to get our hands on it.
