Niall Horan tweeted a photo of Tom Fletcher from McFly playing a purple kids' guitar.
We're taking that to mean the boys spent most of their day mucking around and having a laugh. Which we can forgive them for, so long as they do come up with some tunes for One Direction's new album.
Back when the collaboration was confirmed, Tom Fletcher revealed that he was excited about the prospect of writing for One Direction.
He said: "I can't wait to write more tunes for One Direction as I'm really proud of their success in America I haven't been given a brief as to what kind of song they want from me; we're just waiting to see what I come up with."
