Regardless of whether they're dating or not, Kendall Jenner and Harry Styles are close enough that the E! star is comfortable with the One Direction singer driving her car.

The are-they or aren't-they pair was spotted making a late-night run to Rite Aid in Beverly Hills at around midnight Tuesday night, and eyewitness tells E! News, who saw the two celebs walking out of the store and toward Jenner's black Range Rover.

"They were smiling. They seemed happy together," the source tells E! News, but couldn't say for sure if the duo seemed like a couple. "They looked like they were together, but they could just be friends."

Neither Kendall or Harry walked out with a grocery bag, so it's unclear what the purpose of their visit was, but Styles did take some time out of his quick stop to snap a photo with fans inside. "how do you spot harry styles without dropping your ice cream," a Twitter user wrote with the photo.

The source also explained, "They were waiting to go out [of the parking lot] because they had to give the parking ticket to the attendant," and added, "Harry waved when they drove off."

The two young celebs have been the center of relationship rumors for quite some time now, especially after being spotted hitting the snow together in Mammoth Lakes, Calif., over the weekend. But a source told E! News that Kendall and Harry are "just enjoying getting to know each other. They've been having fun."

In addition to taking to the slopes on Saturday, Jan. 4, Jenner and Styles have also partied together in London and New York City over the course of the last two months. Oh, and a casual drugstore visit.
