Naughty Boy has riled Zayn Malik fans again.
The music producer often courts controversy on social media, posting cryptic messages that get his followers talking.
Earlier today he simply wrote "the devil wears karma", but it was enough to enrage Zayn's fans.
Hoards of Twitter uses flocked to comment, with many making jibes about Naughty Boy's weight.
Others told him to leave Zayn alone, and many suggested he go buy One Direction's new song Drag Me Down; their first since Zayn left the band in March.
The tweet comes after it was announced Zayn, who had been working with Naughty Boy on new music, had joined record label RCA.
Since Zayn's One Direction departure, Naughty Boy has been involved in numerous spats. First he was embroiled in a war of words with Zayn's former bandmate Louis Tomlinson.
"Wow @NaughtyBoyMusic you're so inconsiderate pal , seriously how f**king old are you ? Grow up ! #masterofallwisdom," Louis wrote in March.
"@NaughtyBoyMusic I was talking about the video you tweeted . Clearly trying to wind the fans up ! Well you succeeded anyway . Fair play.
"Anywayyyyyyyyyyyyyy... Always have struggled to bite my tongue (sic)."
The tweets came after the producer posted a spoof video entitled Naughty Boy Saved My Life Zaughty, which is believed to be a mash up of Zayn and Naughty Boy's names.
Naughty Boy replied, promising followers that time will tell the real story.
Next he fell out with Zayn, with the pair parting ways musically. After Zayn slammed him for being "a fat joke", he replied with "dont pretend here when you couldn't defend me there".
