Taylor Swift, Ed Sheeran and Cara Delevingne don't seem likely candidates for a stop at a U.S. ambassador's residence, but there they were, jam session and all. The trio harmonized a cover of The Knife's "Heartbeats" while Sheeran strummed a guitar amid swank surroundings.

Swift posted a snippet of the impromptu performance at what appears to be Winfield House (the official residence of U.S. ambassador to the United Kingdom Matthew Barzun) to Instagram, writing, "Me, Ed, Cara. Singing songs in the US ambassador's house. What is life."

Both Sheeran and Delevingne are British and Swift performed three shows at London's O2 Arena this past week. The singer hobnobbed with Barzun at a benefit concert held at Kensington Palace in November.

Watch the two singers and the supermodel/actress cover "Heartbeats" below.

While they were at it, Swift and Delevingne channeled the first U.S. president.
