The 'Love Story' singer continues her partnership with the drinks giant with a brand new advert.

Taylor Swift is seen writing the lyrics to her new hit '22' in a newly unveiled commercial for Diet Coke.

The 'I Knew You Were Trouble' singer signed an endorsement deal with the drinks giant earlier this year, and a brand new advert was released this week.

The promo opens with Taylor sat on the floor alone writing the song lyrics to her latest 'Red' single, before the advert flicks to fans singing along to the track in places like work or in their car.

Taylor then gets dressed up for a big show and finishes off the track before heading off to perform on stage.

Check out a picture of Taylor writing in the new Diet Coke advert below:

Earlier this week Taylor opened up about her troubles with romance, admitting that break-ups can be "very complex" and explaining some of the emotions she has gone through recently.

Taylor Swift resumed her 'Red' world tour this week as well, alongside support act Ed Sheeran, as they travel across North America.
