The country cuties are showing off their girls!

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.
