After releasing her album Some Lessons Learned earlier this year, Tony winner Kristin Chenoweth cemented her place as a country music star by co-hosting the 2011 American Country Awards on December 5. Donning a boxing robe that proclaimed Chenoweth "Four Feet of Fury," the singer joined her co-host, Trace Adkins, on stage and challenged him to a sing-off. Chenoweth first made the country superstar sing the title song from the Rodgers and Hammerstein classic Oklahoma. She then revealed a surprisingly busty outfit when Adkins asked her to sing his hit song, "Honky Tonk Badonkadonk." Chenoweth even managed to use a bit of her opera training in the hilarious number.
