One Direction have been spending some time in the studio, working on new music for their new album.

No one could accuse these guys of slacking off–they are, after all, in the midst of a huge tour.

One Direction is currently working with McFly, as Niall Horan tweeted about the studio time: “Me, @dannymcFly and @tommcfly made a revelation today!”

McFly singer Tom Fletcher also tweeted on March 6, “Busy times. Spent the morning reading our book about dinosaur poop to a room of adults. Now off to Ireland to make some music with 1D.”

Too funny!

He added the next day, “Recording with @NiallOfficial is always an adventure.”

Danny Jones posted this pic of Niall to Instagram, writing, “Guess who’s in the vocal booth…… ????”

One Direction previously worked with McFly to co-write “I Want” for their first album and “I Would” and “Irresistible” for their Take Me Home album.

This morning Tom tweeted, “Morning. Today’s visitors to our little hotel studio are @zaynmalik & @Real_Liam_Payne. Got lots done yesterday, lots to do today!”

Oh, to be a fly on that wall.
