Kellie Pickler will return to the AMERICAN IDOL stage, to perform her new single, "Best Days of Your Life," which she co-wrote with pal Taylor Swift, on the results show Wednesday, April 8 (9:00-10:00 PM ET live/PT tape-delayed) on FOX.

On her return to American Idol Kellie said, "Going back to American Idol is like going to a family reunion, well, it's more fun than going to my family reunions," she laughed. "Seriously, it's always great to see the gang and feel the excitement from the contestants. And, I'm thrilled to be singing "Best Days of Your Life" which is a blast to perform," she continued.

"Best Days of Your Life," the second single from her self-titled sophomore album, is a sassy revenge song about a cheating ex-boyfriend and is climbing up the country charts. In addition to her performance, Pickler will also be seen on Idol Extra and will make an appearance on On-Air with Ryan Seacrest next week.
