Billboard Music Awards 2017: Red carpet arrivals

It's party time!

Music's hottest stars arrived in style to the 2017 Billboard Music Awards in Las Vegas on Sunday night -- and you better believe they dressed to impress.

The pink carpet was truly a grand affair, featuring more star power than in year's past. Of course, there was no shortage of OMG-worthy fashion moments, with many stars flaunting some major flesh!

Lea Michele flashed her undies in a sheer ensemble, while Rita Ora gave cameras an eyeful with her super see-through bottom.

Noah Cyrus looked oh-so-chic in a matching crop top and trousers combo that showed off her flat tummy. The singer brought her whole family as her dates, and they looked way too cute together!

Jesse James Decker also had jaws dropping as she showed off her curvaceous body in a jumpsuit with some pretty revealing cutouts.
