While Niall Horan tweeted last week about the excitement over what they're working on, it's his latest tweet that has us fidgety.
He wrote last week: "Love this time of year, decisions . Album artwork, album title, music video ideas ! can't wait for you guys to hear and see what we're doing"
Yesterday, he wrote: "Just listening to tracks from the new album! Jesus this is exciting ! really can't wait for u to hear this album! By far my favourite yet"
And, if you needed further proof that their fourth album is going to be amazing, Simon Cowell has weighed in as well, first shooting down his quote about One Direction breaking up, writing: "Just to clear up the rumours it is my guess and my hope One D will stay together for a very long time."
He added: "The boys are having the best time. And as I said recently their new album is really really good."
There's no harm in building a little excitement early but don't keep us waiting too long!
