The 2016 Billboard Music Awards kicked off with lots of style last night at the T-Mobile Arena in Las Vegas. Madonna, Rihanna, Britney are just a few of music industry heavyweights attending one of the biggest music events of the year. Along the amazing music performances from the Billboard Music Awards, our favorite highlight of the event was definitely the celebrity studded pink carpet.

Let's see who was best dressed at the 2016 Billboard Awards and who fell flat bringing hot mess couture to the event.

Ariana Grande arrived to the Billboard Awards wearing an Atelier Versace hatler gown. While the dress is beautiful, she always dresses a little older for her age, and she could've went for a shorter, flirtier frock.

Rihanna in Vintage Thierry Mugler

Rihanna took a risk with the vintage 90s Thierry Mugler brown taffeta dress that she chose to wear to the Biillboard Awards. She rarely hits the mark with her outfits, but this was a rather weird choice for her. Her Manolo Blahnik mules are cute though.

Later, Rihanna changed outfits and wore this Dries Van Noten dress for accepting her Billboard Chart Achievement Award.

Demi Lovato in Chanel

Demi Lovato went for a Chanel look on the 2016 Billboard pink carpet. The "Cool for the Summer" singer wore a lace bustier with wide leg pants and a classic Chanel boucle jacket. Good thing she carried that Chanel clutch which one can easily use to cover a camel toe situation.

Jessica Alba in Zuhair Murad
