Ryan Tedder, who has been working with the 19-year-old singer on a top secret project, has revealed that things could turn awry for the band soon, reported Metro online.
Asked when he thinks Styles will leave 1D, Tedder said, "Oh my God, I have no idea. I have never had any conversations with him or any of them regarding that.
"But we did do something together. I can't say what it is for, though," he said.
The band also consists of Niall Horan, Zayn Malik, Liam Payne and Louis Tomlinson.
