Taylor Swift has released an advert for Diet Coke, where she is seen coming up with lyrics for a song.
The I Knew Your Were Trouble singer is the new spokesperson for the drink and is releasing a series of behind-the-scenes videos with them while she is on her Red tour.
The new video, which premiered on Thursday night, sees Taylor musing over the lyrics for her song 22 as she sips the drink.
As she works through the song, other people in the commercial - such as a man playing the radio in his car and a man making food in a restaurant - start singling along to the track.
The ad ends with Taylor, 23, striding on stage with her guitar in hand.
The singer announced her partnership with the brand earlier this year. She said at the time: "I've said for years that Diet Coke just 'gets me' and my lifestyle. I'm so excited about our new partnership."
