Zayn Malik the only member of One Direction not to congratulate Niall Horan on new solo single

They are all working on their own projects and after Niall announced yesterday (29.09.16) that he had released his debut song 'This Town', Harry, Louis and Liam were quick to show their support.

Louis wrote: "Feeling super proud @NiallOfficial . You sound great ! Great to see you at your bday bash!!,@ while Harry said: "Ahhh, a lovely tune my friend. Congratulations. H."

And Liam tweeted him to say: "good luck boss give him all your support huge day for him proud of you boss (sic)"

But Zayn, 23, remained silent on social media about the song and instead took to Instagram to show off his new hair cut and freshly shaven face.

But Niall didn't seem too concerned about the apparent snub and instead thanked everyone else for their support.

He wrote on Twitter: "What a day today was ! Can't believe the reaction. Crazy s**t !! Celebrating with a beer (sic)"

He later said: "Lying in bed looking at your comments about the song . It's really cool to see what you think n stuff . Thank you."
