Kellie Pickler - ACMs 2009

Kellie Pickler sparkles in a gold Zuhair Murad mermaid gown (complete with a fish-scales print) at the 2009 Academy Of Country Music Awards held at the MGM Grand on Sunday (April 5) in Las Vegas.

The 22-year-old country singer will return to the American Idol stage on Wednesday (April 8) to perform her latest single, “Best Days of Your Life.” Kellie and BFF Taylor Swift co-wrote the song.

“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.”
