Music producer Naughty Boy has released a new song online, featuring Zayn Malik.
Naughty Boy tweeted a link to the song, called "I Won't Mind" along with the words: "let the music do the talking".
One Direction's Louis Tomlinson has accused Naughty Boy of being "inconsiderate" and "trying to wind the fans up", by releasing the song less than a week after Zayn left the band.
Naughty Boy, whose real name is Shahid Khan, has previously worked with Emeli Sande, Tinie Tempah, Ed Sheeran, and Rihanna.
So far, Zayn hasn't spoken about the new song.
