The 19-year-old reality star and Scott, 25, visited the set of DJ Khaled's new music video Tuesday before grabbing a quick bite to eat, according to the Mirror.
Jenner and Scott, a hip-hop artist, wore coordinated all-black outfits, with the reality star in a crop top and athletic pants and Scott wearing a Nine Inch Nails t-shirt and jeans. A bodyguard accompanied the the celebrity pair.
People reported Tuesday that Jenner and Scott enjoyed a casual dinner at Bodega Taqueria y Tequila the night before.
"They were affectionate," a source told the magazine.
Gossip Cop denied a new report Wednesday that Jenner and Scott secretly married this month. The rumored couple were first linked in April following Jenner's split from rapper Tyga, and cozied up at an NBA game the same month.
"It's a fling right now," an insider told E! News at the time. "It hasn't developed into anything yet but they are feeling each other for sure."
Jenner and Tyga called it quits in April after two years of on-again, off-again dating. Tyga appeared to mock the Keeping Up with the Kardashian star in his new song "Playboy," which he released last week.
