While Hunter Hayes and songwriters Dean Dillon and Rodney Clawson were the big winners at the BMI Country Awards in Nashville on Tuesday (Nov. 5), Miranda Lambert's slim figure is stealing the morning headlines. The CMA Female Vocalist of the Year nominee stepped out in a sleeveless black gown tight enough to show off her signature curves ... except the curves stayed home.

Lambert has always embraced her full figure, something country music fans appreciate. But you'll struggle to find anyone criticizing her new look. Mrs. Blake Shelton looks as healthy and happy as ever after obviously shedding some weight over the last several months. It's not clear if she's been on an aggressive exercise and diet plan, or if a life of touring, making new music, adopting animals and opening boutiques has stretched her thin -- literally.

During the awards ceremony, Dillon was named the newest BMI Icon. He's best known for writing over 50 hits for George Strait. Rodney Clawson was named Songwriter of the Year for six big hits in 2013, including 'Drink on It' by Blake Shelton and 'Take a Little Ride' by Jason Aldean.

Hayes' 'Wanted' was named Song of the Year. Justin Moore, the Band Perry, Kacey Musgraves, Jake Owen and Florida Georgia Line also took home gold medallions at the 61st annual ceremony.
