Country stars Taylor Swift and Kellie Pickler, who are real life BFF’s, teamed up for the music video for Kellie’s song “Best Days Of Your Life.” The song will premiere on Kellie’s upcoming album.

Kellie has a similar attitude towards writing songs about her ex boyfriends as Taylor does saying: “You have to be careful when you date a songwriter. We always get the last word!”

While Taylor doesn’t have her own part in the song she does do harmonies on the track and appears in the music video above.

Taylor and Kellie will be hosting the CMA Music Festival: Country’s Night to Rock, which is a two-hour television special which features country stars including Billy Ray Cyrus and Carrie Underwood.
