It looks like Icona Pop's new single will be called 'Get Lost'.
The 'Just Another Night' hitmakers posted the above image on their Instagram last night and even replied to the question "Song???" in the comments underneath with: "Yes yes yessss our new sooong."
As you might be able to see, the sooong is specifically for Sweden, but that's not going to last apparently.
Asked by a fan if it was coming out in the rest of the world, they said: "We promise , just have to start somewhere. And it will be on spotify! X"
So there we are.
