The "Pillowtalk" singer
tells Paper magazine
that at age 23, he now has a different outlook on what he considers sexy. "I've always said it and I still stand by it: I find intelligence attractive. When I learn something from somebody and they teach me something, that's an attractive thing for me," Malik -- who's been dating Hadid since November -- says. "Obviously, I find physical appearance attractive as well, but it's definitely squared more towards a personality as I've gotten older, because you can't have a long-term relationship unless you get on with the person. It doesn't matter really about the exterior."
