The 18-year-old Keeping Up With the Kardashians star and Styles were spotted hanging out in Mammoth Lakes, Calif. Saturday, with Jenner opting for snowboarding and the One Direction singer skiing as they headed down the slope.
A few friends accompanied Jenner and Styles as they made their way down the snowy mountain, walking with the group in heavy coats, Volcom ski gear and snow goggles.
This is the second time this week the duo was spotted out and about together.
The British pop star and Jenner were photographed together for the first time in 2014, posing with a fan named Allie Connolly at a snowboard shop in Mammoth Lakes Friday.
Connolly shared the snapshots via her Twitter and Instagram pages, writing, "Casually hanging out with Kendall Jenner and Harry Styles. #dying."
Although the duo's latest sighting won't do anything to help calm romance rumors, both Jenner and Styles have insisted that their relationship is nothing more than platonic.
"We're friends. He's cool," the model said about the 19-year-old boybander when she attended the American Music Awards in November.
When Piers Morgan quizzed Styles about whether he was dating the brunette beauty after they were spotted sharing a meal Nov. 20 at Craig's restaurant in West Hollywood, Styles played coy, saying, "I mean, we went out for dinner, but no, I guess."
Meanwhile, Kendall's half-brother Brody Jenner gave his opinion about the relationship when he was asked about Styles' reputation as a ladies' man (and heartbreaker).
"I hate to tell you this, but Kendall will be doing the heartbreaking," Brody told the New York Daily News.
"I'm sure she's having a fun time with him," he added. "She has a very level head, great head on her shoulders. But they are both so young."
Since their dinner outing at Craig's, the pair has been spotted hanging out together in London and New York City as well.
