Miranda Lambert and Carrie Underwood showed off their sexy sides at the 2014 Billboard Music Awards, both flaunting major cleavage on the red carpet.
Mrs. Blake Shelton rocked a magenta mini dress with a sheer panel down the front, while the "American Idol" alum sported a chartreuse and silver lace chiffon gown, also featuring a plunging neckline.
The blonde beauties are hitting the stage together tonight to perform "Something Bad" from Lambert's forthcoming album, "Platinum."
