One Direction Niall Horan might be a household name to millions of fans. However, it seems his face remains a mystery to many.

The 1D singer rode the tube recently. Horan also took a selfie while on board public transportation, HollywoodLife reported.

Fans got excited when he posted the pic on Snapchat. Horan signed up for the app recently, Metro reported. However, many wondered why no one recognised him. They posted varied reactions on Twitter. Some admired Horan’s simple lifestyle in spite of fame and fortune, the website noted.

Meanwhile, some were awed at how no one recognised the 1D singer.

Mail Online noted how Niall Horan is spending his days off from One Direction. In contrast to his fellow bandmates, he’s kept a low profile, the website mentioned.

Horan is focusing on other things aside from singing. According to news reports, golf is the target of the 1D member. Horan partners with former US Open champion Justin Rose at Wentworth for the pro-am before the BMW PGA Championship.

Mail Online also reported that his team up with Rose would raise money for Cancer Research UK Kids and Teens. They will hold a gala dinner and golf tournament in May for charity.

“I’m thrilled to team up with Justin to host our first Horan & Rose Gala event, it’ll be great to raise as much money as possible for Cancer Research UK Kids and teens, a charity I feel very strongly about,” Horan said.

“As a golf fanatic teaming up with Justin, a major winner, Ryder cup hero and a great friend, is just so exciting. I can’t wait for this two-day event,” Horan added.

His other bandmates are constantly in the news for various reasons. Harry Styles was again a hot topic when his Instagram post hinted that he was starting a new band.

Liam Payne is reportedly going solo. News of a collaboration with former 1D member Zayn Malik also emerged.

Meanwhile, Louis Tomlinson continues to focus on fatherhood. However, he might also have a new career as the next “X Factor” judge.
