Las Vegas is going to be rocking tonight, as the 2014 Billboard Music Awards are going down at the MGM Grand Garden Arena in Sin City.

The Jenner Sisters made a very fashionable entrance on the red carpet Sunday night, where they both showed some skin. Kendall Jenner, 18, flaunted her trim physique (and some sideboob) in a white cutout cop and sparkly capris -- though her face makeup was a little darker than the rest of her body. Kylie Jenner, 16, looked cute in a white mini that she paired with matching heels and her newly-dyed hair. As for that Band-Aid, we don't know what's going on there.

Jennifer Lopez channeled Little Red Riding Hood, while Carrie Underwood and Miranda Lambert put the girls on display. Danica McKellar took the opportunity to flaunt her killer abs and Nicki Minaj decided to show off some under-boob.

Kesha stood out in a black mermaid-fit ball gown -- looking glam with a pink updo and showing off some serious cleavage.

Chrissy Teigen also showed off a new 'do, sporting blunt bangs and long, straightened tressed that she paired with a white dress with a bizarre design on it. And get a look at her shoes -- loving the snakes around her ankles!

Sarah Hyland and Lucy Hale sported new 'dos too, both of them showing up with sideswept locks that almost made it look like they shaved half their hair off!
