Taylor Swift @ 2008 Country Music Awards

Rising country superstar Taylor Swift attends the 2008 Academy of Country Music Awards held at the MGM Grand Hotel in Las Vegas on Sunday.

At the awards show, Taylor sang, “Should Have Said No,” as she got drenched in water. Check out the video here.

“I wrote this song by myself, and it literally took me just 20 minutes to write before we recorded it,” she says. “I was living every line in this song at the time. I wrote this song about a guy who cheated on me who shouldn’t have.”

The 18-year-old singer won for Top New Female vocalist and dedicated the ACM trophy to her mother.
