Taylor Swift has teamed up with Blake Lively on the music video for her track, I Bet You Think About Me.
The song, which is a "From the Vault" track, is taken off Taylor's re-recorded Red album.
Directed by Taylor's long-time friend, actor Blake Lively, the music video also stars Miles Teller.
In the video, Taylor, dressed in red, crashes an ex's wedding, eventually turning everything red as well.
"Now that we're done and it's over/I bet you couldn't believe/When you realised I'm harder to forget than I was to leave/And I bet you think about me," Taylor sings on the track.
"I finally got to work with the brilliant, brave, & wickedly funny @blakelively on her directorial debut," Taylor shared on Instagram when she teased the video on Monday.
