Zayn Malik's first song since leaving One Direction has been leaked online, leading to a twitter war between producer Naughty Boy and rapper MIC Righteous.

Malik's cover/remix of rap group Rae Sremmurd's No Type features UK rapper Righteous, but producer and frequent Malik collaborator Naughty Boy has alleged that the song had been "stolen" and had nothing to do with Righteous.

Righteous has contested the claims:

Naughty Boy went on to say that the "real" version of the song was coming, a version that Righteous says will feature English rappers Krept and Konan in his stead.

After the song was removed from the web, Righteous re-uploaded it and posted the following to his Facebook page:

"F*** stepping on egg shells cos i wanna keep the label happy.. I ain't signed i can do me...Zayn wants the tune out, he ask me to be on the song, shah (naughtyboy) told me that his label wont let him release any music for the next two yrs..

"So you know what i did? I did it for him, for you. And at the end of the day they cant say no to me, i work for the people not the industry"
