Taylor Swift could not believe that Paul McCartney was jamming to “Shake if Off” at the Saturday Night Live 40th anniversary special after party this past Sunday.
The impromptu collaboration happened when Jimmy Fallon and Taylor Swift joined McCartney on stage for a rendition to The Beatles’ song “I Saw Her Standing There”, then it was just fair to Swift to sing one of her own hits.
Taylor Swift posted a clip of the awesome moment on her Instagram.
Looks like the after party was more fun than the actual show.
