Whether Kelly Clarkson sinks or swims as the host of the 2018 Billboard Music Awards, she can rest assured her showing on the red carpet was a slam dunk.

Clarkson, who will also perform at the show, stunned photographers in a belted black gown with a thigh-high slit. And her followers were more than impressed with the choice of ensemble.

"SKINNY LEGEND WE LOVE YOU YOU'RE DOING AMAZING," one wrote, while another noted: "Wow. I've seen you look beautiful, sexy, motherly but never like this: glamorous. <3 you Kelly, knock 'em dead tonight."
