Thankfully, there is some insider information on the topic of the 1D guys and their manly scents--and the band's opening act, 5 Seconds of Summer, were happy to spill the beans about what Niall Horan smells like.
We feel like this should have some sweeping soundtrack to go with it, because 5SOS really laid on the epic drama of it all, telling Jameela Jamil of Radio 1: "Niall smells amazing but it's the same smell every time, he has a scent. It's overwhelming. You know when Niall's in the room. It's some sort of musk, a cowboy musk. Ireland. Leather bound books. He smells of Guinness."
Well...that's interesting. Musky leathery Irish Guinness. Yum.
