Harry Styles isn’t shy about his extra assets.

In a blink-and-you’ll-miss-it moment, the 18-year-old singer can be seen showing off his third and fourth nipples (!) — which One Direction fans have long been well aware of — in the super group’s new music video for “Kiss You” (around the 2:55 mark).

From multiple news reports to a highly circulated GIF of the shirtless moment, Styles and his chest have been quite the talk of the town since Tuesday’s video premiere.

“I think the big thing is, it’s like in high school… we want to be the same, but having an extra nipple makes you different,” Orlando-based hormone expert Dr. Jennifer Landa told Celebuzz.

“But because [Styles] is willing to be so open about it — and because he’s drawing attention to it and not shying away from it — he normalizes it.”
