Hey, girl. Want to know what you and Harry Styles have in common? Ryan Gosling makes you both swoon. It's been scientifically proven (kind of).

In a recent appearance on BBC 1 Radio, the One Directioner-turned-solo artist-turned actor took on the Heart Monitor Challenge, where he reacted to a series of photos while a medical machine tracked his heart rate. Though Styles fluctuated around 60 to 70 beats per minute, one thing made him spike over 80 bpm: Ryan Gosling.

"Looking very handsome," Styles responded to a shirtless pic of Gosling from The Notebook.

After seeing pictures of Zayn Malik, model Camille Rowe, and even a briefcase full of cash, only one other picture got Styles' heartbeat to race past 100 bpm: Chelsea boots, his signature shoe. Even just looking at the footwear got him flushed.

Harry Styles is one of the handful of stars in Christopher Nolan's Dunkirk, which opens July 21. Watch the dramatic trailer below.
