During a recent interview with Yahoo Celebrity, they were asked about whether they ever go undercover so they will go unnoticed by fans.
Harry Styles said he's not up for it because of the embarrassment factor, explaining, "I think the thing is about a disguise is that if you were to do that, which is kind embarrassing anyway, the amount of embarrassment you would feel after being discovered in a disguise would be too much."
Louis Tomlinson agreed, saying, "It would just be uncomfortable if you got caught out, wouldn't it. 'Oh yeah, I have dressed up as someone else!'"
Liam Payne recommends wearing a baseball cap. Yeah, that oughta do it.
