Following his rendition of the tune, she joined the musician on stage in a silver sequin dress with the words ‘First Class’ stamped in red on the front.
Among those seen busting a move during her set was Taylor Swift, who danced and sang along in the audience.
Jack won the award for Best Collaboration for his song Industry Baby with Lil Nas X during the ceremony.
