Did Naughty Boy post this humiliating pic of Zayn Malik?

Now Naughty Boy, 30, has allegedly gone and added more fuel to the fire by tweeting a humiliating photo of Zayn on Twitter.

The pic sees Zayn, 22, superimposed with curly girl's tresses - no doubt a dig towards his new grey hairdo.

Alongside the photo, Naughty Boy wrote: "Stop making a fool of yo self cuz @ZaynMalik lol #getagrip leave it to the music blud NB #wisdom". OUCH.

But it's possible the music producer had a change of heart, as the tweet was removed shortly afterwards.

However we can always count on good old 1D fans to spot the dig toward the former bandmember, and screengrab it for all the world to see.

The feud between the guys started back in July.

Zayn called Naughty Boy a "fat joke" after the producer got into a few slanging matches with 1D's Louis Tomlinson.

In a tweet back in July, he wrote: "NaughtyBoyMusic you fat joke stop pretending we're friends no one knows you."

That's gotta hurt...

The guys were supposed to be making music together after Zayn quit the band.

Now, Zayn's rumoured to be moving to the US for a solo record deal with RCA, after also recently splitting with fiancée Perrie Edwards from girlband, Little Mix.

He's also said to be trying to bed CBB's Chloe Goodman, after allegedly sending her a message, "do you have a boyfriend at the mo?" according to The Sun.

With all this going on in his life, seems like Zayn's got far biger fish to fry than a tweet from Naughty Boy...
