The 18-year-old sparked dating rumours recently after she was spotted having a cosy meal with the singer, reported Aceshowbiz.
"We're friends. He's cool, yeah, he's cool. It's very hard to have friends of the opposite sex. You go out with one person, you're automatically dating them," Jenner said.
Jenner received hateful messages and death threats from the fans of Styles on micro-blogging site Twitter after the news of the duo's meeting became public.
Recently Styles also denied reports that he is dating the 'Keeping Up with the Kardashians' star.
