The who's who in country music turned out for the 2012 CMT Awards in Nashville, Tenn. on Wednesday night.
Underwood, who took home the award for "Video of the Year" for her song "Good Girl," dazzled in a Randi Rahm cocktail dress embellished with mini silver paillettes and $21,000 worth of Tiffany & Co. jewelry.
Lambert, who worked the carpet with her Pistol Annies girls, chose a strapless Georges Hobeika Signature Collection dress, Giuseppe Zanotti heels, earrings by J/Hadley and bangles by Kara Ackerman.
The host of the evening Kristen Bell wore a gold embroidered Reem Acra gown from the designer's spring/summer 2012 collection and Graziela earrings. (She later changed into a Collette Dinnigan dress during the show.)
Also among the stars without country record deals: Hayden Panettiere, who sported a swingy cream skirt by Praven paired with an embellished Giorgio Armani bodice and black Christian Louboutin heels. "I wish I was in cowboy boots!" the actress exclaimed to Us Weekly on the red carpet.
