Zayn Malik feuds on Twitter with ex-One Direction bandmate

  One Direction is going in a sour direction.
  A Twitter feud has erupted between Zayn Malik and Louis Tomlinson, marking the first time either have indicated there is bad blood after Malik’s abrupt departure from the band in March.
Tomlinson started the feud Wednesday by making fun of a photo that producer Naughty Boy tweeted of himself with Malik which he captioned, "Replace this."
  “Remember when you were 12 and you used to think those Mac filters for your pictures were cool haha ! Some people still do HA!” the singer wrote.

Malik struck back by tweeting, “Remember when you had a life and stopped making bitchy comments about mine?”While Malik has since deleted the tweet, Naughty Boy retweeted his pal’s message. This prompted a scathing back-and-forth between him and Tomlinson.
“And some people can't even sing.. but who's complaining when there's auto tune eh,” Naughty Boy wrote.
“Jesus forgot you were such an in demand producer .... How does it feel to be riding on the back of someone else's career?” the boy bander shot back.
“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,” the producer replied.
“Good for you, well done !!” Tomlinson tweeted. “I think we've done alright in terms of sales and I've happened to write on most. Keep trying!”
It's not the first time that Tomlinson and Naughty Boy have squared off: the teen heart-throb called his producing nemesis "inconsiderate" and worse in March for tweeting that he "saved" Malik from being a boy bander.
The newest social media spat comes not long after Malik deleted all references to One Direction from his Twitter account, prompting an outcry from fans.
