The 23-year-old singer took to Twitter on Monday (19.12.16) to express his dismay that he has developed an infection, admitting it is "not ideal" to come down with an illness so close to the Christmas holiday season.

He told his 28 million followers: "Get a chest infection Christmas week .... cool cool cool ........ not ideal (sic)"

The 'This Town' hitmaker isn't the only member of the popular boy band - who are currently on hiatus - to come down with an illness recently, as his fellow band mate Liam Payne revealed on Saturday (17.12.16) that he too was suffering and unable to get in the studio to work on his solo material.

During a Q&A session called '#AskLiam' on Twitter, one fan asked the hunk: "@LiamPayne how are you today? #askliam (sic)"

To which the 23-year-old singer replied: "@1DGlobalPH I am at home and am sick so I can't record at the moment (sic)"

But Niall's chest infection won't hinder his music career, as he recently said he would be taking a few months off to be with his family and friends before he gets back into the "writing zone" in February.

He said: "I'm gonna head home and chill out as it has been hectic the last few months. Looking forward to getting home home at Christmas. I haven't been home since last Christmas so I miss everyone and hopefully this year I'll get to spend some quality time with family and friends.

"I really do wish I could spend more time at home but with Ireland as small as it is, I sometimes struggle to relax so fingers crossed because I miss that place a lot. After Christmas, I'm gonna fall off the face of the earth and do one of my disappearing acts. I want to come up with more song ideas and get back in the writing zone. So have a lovely Christmas and happy New Year and I'll see ya in Feb. (sic)"
