The 19-year-old One Direction member is in the US promoting the band's new album Midnight Memories, and decided to take a moment to meet up with the Keeping Up With The Kardashians star, 19, whom he met at The X Factor USA.
The twosome was later spotted driving off together in a black Range Rover.
Upon learning about Styles' outing, One Direction fans immediately took to twitter to express their discontent with his apparent new love interest.

In other Kendall Jenner news, the 19-year-old model also made headlines Tuesday after Australian photographer Russell James posted a racy Instagram picture of her seductively posing in a sheer top.
