Pete Davidson and his new girlfriend Elsie Hewitt have an international love ... because they flew out to Scotland together for Dave Navarro's wedding.

The comedian's girlfriend just shared a bunch of photos and videos from their trip to Scotland, where they were among the guests for Dave's nuptials to fashion designer Vanessa DuBasso.

Pete and Elsie took a romantic stroll through the countryside, stopping to feed a horse on a farm some carrots. In one video, Pete looks around at the landscape before turning to the camera and joking, "They have this s*** in the Bronx you know."

Elsie also shared some candid moments with Pete ... including a mirror selfie video where they dance as they check their reflections ... and another clip from a hearty laugh in bed, where Pete cracks her up about "the guy with the oboe."

The 'SNL' alum's model girlfriend even appeared to post a shot from Dave's wedding ... a candlelit dinner table decorated for a celebratory meal.

Dave and Elsie have only been official for a couple weeks now, but we've already seen them together in Florida, New York and the United Kingdom.
