Louis Tomlinson hits out at Naughty Boy for posting Zayn Malik's first solo single demo online

Naughty Boy posted a link to a demo of his and Zayn's new track 'I Won't Mind' on Twitter and attached the caption: "let the music do the talking guys. thank us later. :) x (sic)"

But the link left Louis fuming and he tweeted his disgust at the record producer, claiming he was trying to upset One Direction's fans.

He wrote: "Wow @NaughtyBoyMusic you're so inconsiderate pal , seriously how f***ng old are you ? Grow up ! #masterofallwisdom

"I was talking about the video you tweeted . Clearly trying to wind the fans up ! Well you succeeded anyway . Fair play (sic)"

Naughty Boy also posted a picture of a cryptic quote, but several 1D fans reacted in fury to the post.

The quote read: "Respect yourself enough to walk away from anything that no longer serves you, grows you, or makes you happy."

irwinstation tweeted: "@NaughtyBoyMusic you have zayn congrats now stay away from the boys they're doing a big work for us and you just are so annoying (sic)"

Louis, 23, later took to Twitter again to change the subject by thanking the One Direction fans - known as Directioners - for their support.

In a series of tweets, he wrote: "Always have struggled to bite my tongue

"Anywayyyyyyyyyyyyyy

"Big love to all our fans ! Seriously thank you you guys have been unbelievable , can't wait to play Cape Town . Gonna be a BIG show !!! (sic)"

The demo release will not come as a surprise to some as Zayn and Naughty Boy were spotted at a London recording studio just last weekend.

However, several fans will be shocked that Zayn is working on new material so soon after quitting the boy band as he stunned the music world last Wednesday (25.03.15) when he announced he had left the group for good, insisting he wanted to lead a "normal" life "out of the spotlight".

He said: "I am leaving because I want to be a normal 22 year old who is able to relax and have some private time out of the spotlight. I know I have four friends for life in Louis, Liam, Harry and Niall. I know they will continue to be the best band in the world."
