One Direction still see themselves as newcomers and say they are too inexperienced to mentor wannabes on The X Factor.
The global chart-toppers, who earned £100 million in two years, have reportedly declined an offer by boss Simon Cowell to mentor contestants on the show because they are too inexperienced.
Newly single Louis Tomlinson told The Sun: "We don't feel like we are in a position to be giving strong advice."
Simon is said to have been hoping the boy band would guest star in an episode to conduct a master class with the current group of wannabe stars to help boost the show's ratings.
The singers recently appeared on both the Australian and US versions of the series, where they were a huge hit.
Harry Styles said the group really enjoyed being guest judges on the Australian X Factor, saying the experience was "really cool and fun".
But One Direction are said to have ruled out a similar appearance during the current series of the British show on ITV1.
