Country's biggest global star Taylor Swift is currently completing a 13 hour fan day at the downtown arena in Nashville. Demand from fans for a photo opportunity and autograph has become too big for the CMA Music Festival's Convention Centre venue and she needed to move to a bigger venue.

Swift has been meeting fans all day and well as performing a few acoustic tunes. She is expected to sign over 2,000 autographs.

Her new iPhone app is also being launched today which gives fans the opportunity to re-mix two Taylor Swift tracks and even record their own version.

Swift will have a new album out before the end of the year.
