McBusted have been busy working on new music with All Time Low.

The supergroup - made up of Busted members James Bourne, Matt Willis and McFly - are currently in the studio recording a joint LP, with ex-Busted boy Charlie Simpson recentlyconfirming: "From what I understand I don't think it's a full-time thing for them...

"I'm not sure what their long-term plan is but I do know their short-term aim is release an album."

And, it seems their LP is coming along nicely with All Time Low frontman Alex Gaskarth taking to Twitter to confirm their session together.

Had a blast working with the @mcbusted dudes today! Good vibes all around.

Really enjoying getting to write for some other bands / artists. Takes you out of your comfort zone, keeps things fresh! I feel ALIVE(erect)
