While he's currently dating supermodel Gigi Hadid, the former One Direction star, 22, still spoke about the qualities he likes in a girlfriend during a new interview with Billboard.
"I need a challenge," he said. "Also, I like girls that are a bit chunky in certain areas - the nice areas. I like a fuller woman.
"I enjoy an intellectual conversation as well, where someone can construct a sentence beyond what hair and makeup they're wearing, and talk about something political or about the world. I like an opinion."
Zayn and Gigi were first linked at the end of last year and while they initially claimed to just be friends, the cosy selfies and frequent outings in recent weeks have suggested it's something more.
Prior to that, singer Zayn was engaged to Little Mix star Perrie Edwards, but they broke up in July last year, shortly after he quit One Direction.
Zayn quit 1D in March, during their world tour, and is now getting ready to release his debut solo album later this year though RCA Records.
