Looks like the war between Zayn Malik and Louis Tomlinson is on! It seems like the former band mates are in a legitimate fight, after they, as well as Louis and Naughty Boy exchanged argumentative tweets on Wednesday.

In a tweet Zayn Malik wrote directly at Louis, he sarcastically asked if Louis remembers having a life and did not make "bitchy comments" about his.

The drama started when music producer Naughty Boy shared a photo of himself in the studio with Zayn Malik and captioned it with, "Replace this." The caption seemed to be a nod to the unconfirmed rumor that One Direction is looking for a new member to replace Zayn after he decided to leave the band last month.

Zayn Malik then also posted the photo on his page, which made fans think that the tweets were a possible reaction to the Instagram video posted by Liam, in which he joked about having a fifth member.

Louis seemingly responded to the photo and wrote on his Twitter account, "Remember when you were 12 and you used to think those Mac filters for your pictures were cool haha! Some people still do HA!"

Not letting Louis' tweet slide, Shahid Khan, Naughty Boy's real name, then fired back and said, "And some people can't even sing... but who's complaining when there's auto tune eh." 

The Twitter war, however, did not end there. Louis responded just a few hours after and mockingly asked the producer how it feels to ride on somebody else's career, which was the tweet that incited Zayn Malik's response, which he directed to Louis.

This is not Louis and Naughty Boy's first Twitter war. Not long after Zayn Malik's departure, Louis accused Naughty Boy of attempting to wind up fans, which ended with Naughty Boy leaking a song that Zayn recorded on his own.

When they were still in the band, Louis was the one closest to Zayn Malik, which left Louis the most worried when he unexpectedly made the decision to leave. The best friends even got matching inks. Louis had the word "Bus 1" tattooed on his right arm, while Zayn's is on his left hand.
