Miranda Lambert is smokin'! The country superstar looked sexier than ever at the 56th Annual Grammy Awards on Sunday, Jan. 26, where she showed off her dramatically slimmed-down figure in a scene-stealing red gown.
The Best Country Solo Performance nominee -- who is scheduled to perform with Billie Joe Armstrong during the show -- turned heads in a custom Pamella Roland dress with a plunging, cleavage-baring deep-V. She accessorized the look with a red clutch, silver bangles, and turquoise-accented hoop earrings.
The "Mama's Broken Heart" singer first flaunted her skinnier physique in a little black dress at the BMI Country Awards in Nashville, Tenn., back in November. The next night, at the Country Music Awards, she rocked a brilliant blue Robert Cavalli gown.
"My wife is so hot it's ridiculous," her husband, fellow country star Blake Shelton, tweeted at the time.
"Like I have always said, it's not about a scale, it's about how you feel and how your jeans fit," Lambert wrote on her blog. "And on November 10th when I turned 30, my skinny jeans were finally baggy! Mission accomplished!"
