Today Harry Styles played a Tiny Desk Concert at NPR. Really, all I could see was his hair. But he does have impressive hair. Can’t wait to see the video when it posts! pic.twitter.com/WTgVj2Ltb9

NPR Music regularly invites artists to perform in its office. Styles also explored some other areas of the building.

Did not get to see the Harry Styles Tiny Desk, but he did linger by my desk for a second.

Overheard him saying he liked the open office plan, making Harry Styles the first person in history to like open office plans. pic.twitter.com/9M6yfq5OEG

Once a member of the British boy band One Direction, which rose to international stardom after coming together on music competition show The X-Factor, Styles released his first solo album in 2017. Earlier this month, Styles made headlines with a moving performance of a ballad off his sophomore solo album at the BRIT Awards in London.

His visit to the District was first made public by a fan whose friend took an evening class at Barry’s Bootcamp, a boutique workout that counts celebrities like Styles, Kim Kardashian, and David Beckham among its fans. When the tweeter’s friend asked Styles for a photo after the class, he politely declined, according to her tweet. Pictures and videos then surfaced of Styles in the studio grabbing a smoothie.

SHE WENT UP TO HIM AND SAID “has anyone ever told you you look a lot like harry styles” AND HE WAS LIKE YEAH THEN SHE ASKED FOR A PIC AND HE POLITELY DECLINED BC HE WAS SWEATY BUT HE HAD HIS HAIR UP IN THE CUTE PONYTAIL AND HE WAS WEARING A BLACK SHIRT AND BLACK PANTS https://t.co/w4gaMCX0j0

Styles doesn’t have any upcoming performances scheduled in the D.C. area—his next international tour isn’t set to begin until April. One popular theory is that he is in town to perform at NPR’s Tiny Desk Concert. NPR has not responded to a request for comment. Whatever the reason for the visit, it has D.C. fans losing their minds.

Harry Styles was spotted in DC last night…. God, I don’t ask for much, but I’m begging for one thing and that is to somehow bump into Harry Styles on my 7:30 commute to work
