Harry Styles just ended his quiet era in the most Harry way possible. No big announcement, no rollout, just an unexpected YouTube upload titled "Forever, Forever" that immediately sent fans into detective mode.

Harry Styles surprised fans with a YouTube video upload of the piano ballad he performed on the final night of his Love on Tour.

In September, Styles — who’s been romantically linked to Zoë Kravitz since August — ran the Berlin Marathon, but under a different name: Sted Sarandos. At the time, when he was spotted sporting a headband and sunglasses, he crossed the finish line in two hours, 59 minutes, and 13 seconds.
