Published Date:  06 April 2009  Carrie Underwood was named Entertainer Of The Year at the Academy of Country Music Awards in the US.  The former American Idol winner was the first female act to win the honour since the Dixie Chicks in 2000. "I've had a lot of good moments in the past four years. This one takes the cake," the tearful 26-year-old said.   "Thank you God, thank you fans, thank you to ACM for nominating me in the first place. I never thought I'd be nominated and never thought I'd win. I'm shaking. I don't know what to say."
