From serious side boob to spiky hair, some ladies went all out with their pink carpet looks at the 2016 Billboard Music Awards!

Jessica Alba wore a Zuhair Murad dress, Stuart Weitzman boots and Cartier jewels, but it was her slicked-back hairdo that made her stand out. Ok, and the boots were pretty hot too, but otherwise she kept her look mostly conservative. On the other hand, Ciara, one of the show's co-hosts, was anything but! The sultry singer wore a Philipp Plein dress with Casadei shoes and her tatas were practically hanging out of this metallic frock. Hey, if you've got it, flaunt it?

Unlike Jess and Ciara, Ariana Grande had the perfect mix of sexy and funk in a Atelier Versace gown, but she had a less-than-graceful moment on the red carpet when she nearly tripped and fell on her face. Oops! Watch her near-miss in the video below:
