Louis Tomlinson sides with Calvin Harris in Zayn Malik Twitter spat leaving One Direction fans in shock

They had a Twitter spat after Zayn Malik left One Direction and now it looks like Louis Tomlinson and his former bandmate could be at war again. 

After Zayn, 22, got into an argument with Calvin Harris, 31, on social media, Louis,23, waded in, showing his support for Calvin by favouriting the Scottish DJ's tweet. 

The feud started when Malik retweeted a post comparing Taylor Swift's refusal to stream her music for free with a quote from Miley Cyrus saying she doesn't care about money. 'The difference is astounding,' wrote the poster.

A furious Harris was quick to defend his girlfriend Taylor, writing 'You've made your money? Cool... f**k the 99% of musicians who depend on these

services to survive, right? Yeah f**k em.'

This quickly deteriorated into a war of words with Zayn and while it was going on, Louis favourited Calvin's tweet. 

Fans of 'Zouis', the bromance between Zayn and Louis were left utterly devastated, taking to Twitter to share their torment. 

weets included: 'zayn put his differences aside and congratulated 1d for drag me down but you decide to shade an old friend ok @Louis_Tomlinson?' and '@Louis_Tomlinson that tweet is ugly unfav it.' 

Another referenced the news that Louis is set to have a baby with stylist Briana Jungwirth pregnant and wrote: '@Louis_Tomlinson Stop worrying about what Zayn does & go worry about your baby mama & unborn child that you'll be supporting for 18+ years'.
