The fan-favorite engaged pair posted on their Instagram Stories photos and videos of each other acting adorable on a shopping trip in New York City on Friday.
Davidson shared a photo of the two inside a car, with him wearing a lilac hat and sticking out his tongue, while she sports a white visor and smiles widely.
"Hat? Check," he wrote.
Grande posted a selfie video of the two goofing around some more in the vehicle.
The couple headed to a Sephora store. Grande shared a video of the two crouching in one of the makeup aisles and then standing and making silly gestures at a swarm of paparazzi crowded outside the windows.
