Harry Styles, who in recent years has come out as sexually fluid, was subject to a heart monitor challenge for BBC Radio 1, and as it turns out the sight of Chelsea boots and a shirtless Ryan Gosling were the only things that made his wee little fluid heart flutter.

After being strapped to a heart rate monitor, he was shown a series of images to see what would elicit a response.

Once he saw Ryan Gosling shirtless in The Notebook, Harry’s heart rate increased intensely, up to 80 beats per minute. A Chelsea boot had an even higher reaction, going up to 102.

Thankfully, the host ended up giving Harry a copy of the photo of the shoes (what a great host!).
