Taylor was spotted on set in London on Saturday night, where she was seen filming on a double-decker bus, in a cab and on a bike atop the Millennium Bridge, TMZ reports.
Taylor has been spending *a lot* of time in London of late.
She recently hosted a top secret listening party for a select few lucky fans, and now she's chosen the gorgeous city as the setting for her next music video for an unknown single.
Is it possible that she's spending more time across the pond to see her British BF, Joe Alwyn? Could the single be inspired by him? We'll soon find out...
