Zayn Malik SLAMS Naughty Boy on Twitter: “You fat joke – nobody knows you!”

Zayn Malik has completely bodied his friend Naughty Boy on Twitter after the producer apparently uploaded a video featuring the former One Direction singer.

Taking to Twitter this lunchtime, Zayn branded Naughty Boy – real name Shahid Khan – a “fat joke”.

What the actual hell?!

Before Zayn's outburst, Naughty Boy had written:

It looks like - in Zayn's eyes at least - Naughty Boy had something to do with this leaked video of him singing on Krept & Konan's No Type video, especially as in the first part of the clip you can see someone sitting in front of their computer filming the footage on their phone.

It comes after rumours that Zayn was planning on ditching NB and surround himself with professionals from the music industry to help launch his solo career - even though it's thought he's legally obliged not to release anything for two years after quitting 1D.

According to the Mirror, Zayn's been in talks with management and production expert Sarah Stennett, who has worked with Jessie J, Rita Ora and Ellie Goulding in the past.

A source told the newspaper that Sarah "won't want anybody around who is too much of a livewire or keeps gossiping", which pretty much rules out Naughty Boy going forward.

Speaking over the weekend, Konan of Krept & Konan explained how the rappers first met Zayn a year ago because they were all always in Naughty Boy's studio.

"Zayn was there sometimes so we chilled together. Zayn's down-to-earth, but then everyone is normal underneath," he said.

"I feel Zayn is good talent and I’m intrigued to see what he’s going to do next with his music."

Konan added that they'd even recorded a video together, saying: "We were just rolling the camera, having fun."

Looks like this could be the video in question...

Whatever's happened over the weekend, Zayn and NB have unfollowed each other on Twitter now, so it's looking pretty serious.
