According to The Sun, the Someone Like You singer was seen at the iconic studios - where the soundtrack is being put together by composer Thomas Newman.
Newman has previously worked on music for movies such as American Beauty, The Shawshank Redemption and WALL.E.
The 24-year old - who is expecting her first child with boyfriend Simon Konecki - has previously been linked to the project, with reports back in October 2011 claiming she had already started writing her Bond track.
He added: "I can’t think of a better one. She’s phenomenal and it’s nice, in a day and age where so many vocals are fixed by computers, that the biggest album of last year was somebody who sings for real.
“I would hate to see music become more mechanistic and less human, so her success has been great."
