Zayn Malik and Louis Tomlinson are fighting on Twitter

Zayn Malik, Louis Tomlinson and Naughty Boy are having a row on Twitter.

It seemed to start when Naughty Boy posted a picture of himself and Zayn along with the caption, “Replace this” – which Zayn then retweeted.

Louis then wrote: “Remember when you were 12 and you used to think those Mac filters for your pictures were cool haha ! Some people still do HA!”

Zayn then replied directly to Louis, saying: “Remember when you had a life..?”

Naughty Boy, who has been working with Zayn, also had his own back-and-forth row with Louis on the social network.

Naughty Boy is said to be working on new material with Zayn, who quit One Direction in March.

The music producer has already upset One Direction fans, by sharing a video online which seemed to suggest that he had “saved” Zayn from the band.

Louis accused Naughty Boy of being “inconsiderate” to fans after he posted the link.

A song featuring Zayn without the rest of One Direction was also taken down, less than a day after it was shared on Soundcloud.

Naughty Boy tweeted a link to the track, with the words “let the music do the talking” – less than a week after Zayn revealed he was leaving One Direction.
