Country music's biggest names hit the red carpet in Las Vegas for the 2012 American Country Awards.

Lady Antebellum's Hillary Scott, who recently announced she's pregnant with her first child, showed off her changing curves in a form-fitting black dress.

LeAnn Rimes also chose the conservative color -- a smart move the day after an emotionally draining interview aired portraying her as someone who was sorry for her actions. Still, the svelte singer managed a smile as she arrived.

Carrie Underwood loves to razzle and dazzle. Opting for a tangerine mini, Carrie bucked the black trend. Some might think her dress looks a little chintzy, but that dubious honor belongs to Miranda Lambert
