These two just can't seem to get enough of each other. On midnight Tuesday night, Harry Styles was photographed driving his rumored girlfriend Kendall Jenners black Range Rover for a quick Rite Aid stop, E! News reports, and apparently they "looked happy together."

"They were smiling," said an eyewitness. "They looked like they were together, but they could just be friends."

For months fans have been wondering whether or not 19-year-old Styles and 18-year-old Jenner are or aren't together, though they are clearly close enough for the singer to be driving her car. On Tuesday night, the pair walked out of the Rite Aid with a grocery bag after Styles took some time to take photos with fans inside.

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

Last weekend, Jenner and Styles were stopped enjoying a ski trip together in Mammoth Lakes, Calif. while reportedly staying at a friends house. Witnesses reported lots of flirting and touching, and rumor has it that Jenner's family, including her big sister Kim Kardashian, are keeping an eye on the pop singer just in case he breaks her heart. Last year around this time, Styles was cozying up to his then-girlfriend Taylor Swift, who was reportedly upset that he'd chosen to spend the holidays with Jenner instead of her.
