Swift And Pickler Record Duet

Country superstars TAYLOR SWIFT and KELLIE PICKLER are joining forces to collaborate on a new track for the former AMERICAN IDOL star's upcoming LP.

The pair have penned a track together, entitled Best Days Of Your Life, and will record the song for Pickler's as-yet-unnamed album, which is due to hit record stores later this year (08).

Swift and Pickler wanted to record a song which hits out at ungrateful ex-boyfriends, with Pickler warning future suitors, "You have to be careful when you date a songwriter. We always get the last word!"

The duo became close pals after regularly seeing each other on the country music circuit, and are set to co-host CMA Music Festival: Country's Night to Rock, which will air on U.S. TV in September (08).

And there is another reason the two singing sensations are good friends, mischievous Pickler insists she behaves herself when Swift is present: "When I hang out with Taylor, I don't get in any trouble."
