Carrie Underwood kicked off the American Country Awards red carpet in Las Vegas tonight. She wore a playful white Maria Lucia Hohan number while Jordin Sparks also went with the neutral hue. Kristin Chenoweth, who cohosted the evening with singer Trace Adkins, chose a bright plunging green gown by Honor. Kristin started off the show with a funny skit and then handed the microphone to Jordin. Jordin presented the first honor of the night, Single of the Year, to Carrie Underwood, for "Mama's Song." It was just the beginning of the winning for Carrie, who picked up two more Fender guitar statues before the show wrapped up. Other country performers recognized at the 2011 ACAs included Lady Antebellum, American Idol's Scotty McCreery, Brad Paisley, and Blake Shelton.
