Also, Kellie Pickler returns to the Idol stage to perform her new single, "Best Days of Your Life".

Kellie Pickler's gold-certified album, Small Town Girl, became the best-selling debut in 2006 by a solo country artist. Two of the album's singles, "I Wonder" and "Red High Heels," placed on Billboard's Hot Country Songs Top 15 chart. Kellie's self-titled sophomore album recently debuted at No. 1 on the Billboard Country Album Chart, making her only the sixth country artist to have their debut and follow-up albums enter at the top of the charts. Winner of three 2008 CMT Awards, Kellie penned five of the album's tracks, including the hit "Best Days of Your Life," which was co-written by Kellie's friend and mega star Taylor Swift. Taylor, who also lends her background vocals on the record, will appear with Kellie on the "Fearless Tour 2009". The six-month tour will visit 52 cities in 38 states and provinces across the U.S. and Canada.
