The One Direction lads continue to take the US by storm, but success comes at a price as the boys struggle to keep up with endless late nights, gigs, promotional appearances and constantly being on the road, supporting Big Time Rush.
Harry, Liam, Zayn, Niall and Louis are relishing every minute of life across the pond and being number one and two in the iTunes album chart, but Harry has admitted that their hectic schedule can occasionally, literally, be a pain in the butt.
During an interview with the Daily Mirror, the 18-year-old explained that he was nursing a sore throat, croaking: “I get ill all the time – it’s all the travelling and long distance flights.
“Four of us had to have vitamin jabs because we were run down. I had mine in my bum. I do get homesick, too.”
Niall Horan agreed, saying: “This is the longest we’ve ever been away from home and it’s hard.
"We miss our families, we miss our friends. We get homesick, massively so.”
Liam Payne echoed the sentiment as he said: “There’s a part of me that occasionally wants to go back to Wolverhampton and just chill out, play the field, be normal again. Just chill out…”
The boyband-of-the-moment wouldn’t be human if they didn’t occasionally want time off, but for now, they are having a ball and loving every opportunity that comes their way.
Liam was quick to add: “But I know how incredibly lucky I am, how privileged I am to be doing this.
“It is all massively exciting. I would never want to sound ungrateful to anyone, especially to the fans.”
