Miranda Lambert donned not one, but two spectacular outfits for an appearance at the 'Fashion Rocks' event Tuesday night (Sept. 9). The 'Mama's Broken Heart' singer went from red carpet sexy to performance sassy in dazzling black and red ensembles.

Lambert made jaws drop as soon as she hit the red carpet in a black suit with leather panels that was both classy and sexy. We couldn't help but stare at the opening of her jacket, though ... Her sparkly silver and black bra peeked out from under her sleek suit. It was definitely the look of the night!

Of course, Lambert's makeup was also flawless. She kept her (new)  blonde bob simple and straight, only adding a splash of color with her red nails.

But for her performance, the blonde bombshell amped up the look to just plain sexy. During the concert event that joins fashion with music, Lambert delivered a smokin' version of 'Little Red Wagon' in a little red romper. The red jumpsuit showed off her killer body -- especially her tiny waistline and very fit legs (Blake Shelton, you are one lucky man!). The halter romper let the audience catch a little peek of her toned tummy via a triangle cutout. On her feet, Lambert wore a shiny pair of gold booties with a thin black heel.

Lambert wasn't the only country star asked to join in on the 'Fashion Rocks' event. The Band Perry, who are always fashionable, were also in attendance. Luke Bryan also came with his wife (who looked fabulously fierce in red), delivering a performance, as well.

But no one -- no one -- stunned quite like Lambert!
