he rather unexpected bonding session occurred backstage after the awards ceremony, where Lady Gaga was pictured chatting away with Harry Styles and the gang, pausing to pose with the British boys in her final get-up of the evening - a Botticelli Venus-esque costume made out of a seashell bikini and voluminous, tumbling golden waves.
And it looks like the 1D boys made an impression on the US star, who opened the star-studded night with a rendition of her latest single, Applause.
Following the show, Gaga sent out a message cementing their newfound friendship, tweeting: "You know what @onedirection? Your fans REALLY love you, and it's beautiful to see! Enjoy your Moonman! Love, Seashell Girl *winks* xx" - which was swiftly retreated over 130,000 times.
Lady Gaga wasn't the only celebrity One Direction cosied up to over the course of the evening however, with teen heartthrob Harry Styles also pictured with Taylor Swift, Ed Sheeran and Rihanna. Phew! SM
Watch One Direction's best moments...
