Louis Tomlinson, Zayn Malik, Naughty Boy Twitter Feud! Former BFFs Fight - 2015 One Direction Break Up Rumors Erupt

After Zayn Malik quit One Direction earlier in 2015, rumors of the boy band breaking up for good started to erupt. So far, 1D has soldiered on as a four-piece made up of Louis Tomlinson, Harry Styles, Liam Payne and Niall Horan, but who knows how long that will last. In fact, former BFFs Malik and Tomlinson were just caught up in a devastating Twitter feud that also involved Zayn's new pal, producer Naughty Boy! When will the pain stop?

As Defamer points out, just about a week after Malik left the biggest boy band in the world, Naughty Boy shared some demos that he and Zayn recorded. Tomlinson didn't really appreciate this, and started a public battle with the pop music producer on Twitter.

Here is the first Twitter interaction that started this feud:

Wow @NaughtyBoyMusic you're so inconsiderate pal , seriously how fucking old are you ? Grow up ! #masterofallwisdom

We're not sure if Naughty Boy ignored Tomlinson or what, but this week he posted a pretty sharp jab on Twitter: a photo of Zayn and himself in the studio with the caption, "Replace this." Check it out right here:

From there, Louis and the producer had a bitter back-and-forth tweeting fight, with each trying to bash the other while also bragging a bit about themselves (more so on Naughty Dog's side of the argument). Check out these Twitter posts right here:

Remember when you were 12 and you used to think those Mac filters for your pictures were cool haha ! Some people still do HA!

@NaughtyBoyMusic Jesus forgot you were such an in demand producer .... How does it feel to be riding on the back of someone else's career ? — Louis Tomlinson (@Louis_Tomlinson) May 6, 2015

@Louis_Tomlinson Yeah how does it feel mate? You've been doing that for the last five years... I've got Emeli Sande and Sam smith on my CV

Perhaps the worst part of all of this is that Zayn has chosen his side. The former member of One Direction called out Louis in this tweet:

@Louis_Tomlinson remember when you had a life and stopped making bitchy comments about mine ? — zaynmalik (@zaynmalik) May 6, 2015

Let the river of tears begin!
