Turns out the two of them met last summer when she was working on her Burberry campaign, and they kept in touch while she went to school at Brown this past year.
"We’ve been friends since the Burberry shoot. And when I was in the states, George was taking me through a lot of his music as he was recording it," she told UK's Radio 1. "I couldn’t believe [how good the music was]. I’m a big fan. Everything he did was amazing."
"I went to see them play at Northampton at the Road Menders," she told BBC. "It was a pretty intimate gig but it was really nice. I'm going to try and see George [when One Night Only] plays at Reading [festival]."
As for that cameo in the music video, Emma said she "really wanted to be involved somehow" with the band, and that she and George were "really pleased with it."
Are you happy to see Emma with a rocker boyfriend? Were you surprised to find out she went to Glastonbury?
