Cue the sound of girls screaming around the world.
The former One Direction star attended the opening of Christopher Nolan's new WWII epic, in which he makes his acting debut as the character of Alex.
Since Styles has not made many public appearances of late, fans went wild for his sharp appearance at the premiere.
It was a, quite frankly, lovely moment when Style's emerald peepers locked onto the Prince's own azure eyes and they shook hands and had a natter.
It's not the first time they've met - as many assumed.
Prince Harry asked the then long-haired Styles: "When was the last time you had a haircut?" They hooked up in 2015 at a Royal concert event in London.
"We're not trying to oversell Harry [Styles] in the movie for the specific reason that it's an ensemble", Nolan explained. "I'd do this one (film) again, for sure. but it may be one and done for me", he said, before meeting royal namesake Prince Harry on the red carpet.
