Scarlett Johansson is fascinated by men’s nipples, reports. The He’s Just Not That Into You actress can’t understand why boys still have them, adding the concept of male nipples completely baffles her.

She is quoted by the Chicago Sun Times newspaper as saying: “The one thing I don’t understand about men is nipples. I don’t know if there is one aspect of men that I don’t understand other than why they have nipples.

“Honestly, why? I guess it has something to do with the X chromosome.

“What is the function of the male nipple? Maybe we all start as androgynous creatures and then they become men?”
