Jaw. On. Floor!!!
She couldn't have looked more perfect in her festively embellished Jaime Lee two-piece outfit that clung tightly to her sexy curves!
Yeah, baby! Show 'em how it's done!
The skirt also featured sheer mesh side panels that gave us naughty glimpses at Katy's thighs!
But it wasn't just the ensemble that took our breath away -- we were equally delighted by her bold plum lips and the dark blue A-Esque knotted headband in her hair!
And her second look of the night was just as awesome!
Katy changed into a black Kokon To Zai dress decorated with cameo portraits to present the award for female artist! She even had time to rework her hair into a two-toned ponytail!
Her delicate nose ring and the sparkly jewel on her tooth were the cherry on top of two perfect outfit sundaes!
She just slayed us so hard!
