Former One Direction star Zayn Malik seems to have fallen out with collaborator Naughty Boy.
The singer, who quit the boyband earlier this year saying he wanted to be a "normal 22-year-old", has previously spent time in the studio with Naughty Boy - real name Shahid Khan - who put a track featuring Malik singing over an acoustic guitar online after he quit One Direction.
But now Malik has tweeted the musician saying: "You fat joke stop pretending we're friends no one knows you."
