Kellie Pickler and Taylor Swift Team Up for Song

Kellie Pickler is teaming up with fellow country star Taylor Swift for a new song on the former Idol’s upcoming album.

On the track, the singers mine some ex-boyfriend territory for a get-back tune called “Best Days of Your Life”. Although Pickler is mum about exactly which ex the song refers to, she tells People, “You have to be careful when you date a songwriter. We always get the last word!”

While we wait to hear that track, let's focus on Kellie's current single "Don't You Know You're Beautiful", which continues to climb country radio slowly but steadily. Again, expect the album to hit stores this fall.

Can't wait to hear that song, I've got a feeling it will end up being Pickler's biggest hit yet (if released as a single.)
