Music's hottest chart-topping artists gathered in Las Vegas on Sunday night (May 22) for the 2016 Billboard Music Awards. And everyone from The Weeknd to Ariana Grande attended the event that celebrates the artists who've managed to soar up the charts over the past year.

While Wiz Khalifa and The Weeknd have already picked up awards, one can't deny that many of your favorite singers and rappers, who strolled down the red carpet, were looking pretty good. From the silver sheath that the night's co-host and newly betrothed, Ciara, wore to Kelly Rowland's crystal-encrusted gown, the ladies brought the glam.

Meanwhile, the guys ran the gamut of casual comfort or full formal wear like Billboard Music Awards host Ludacris donned at the event.

Check out the stylish frocks and suits worn on the red carpet at the 2016 BBMAs in the gallery above.
