Charli XCX is sultry in a black dress at the 2015 Billboard Music Awards

Music's sultriest diva Charli XCX arrived at the 2015 Billboard Music Awards held in Las Vegas in one of her usual slinky attires.

The dark-haired beauty sizzled in a vintage black gown with spaghetti straps that was figure-hugging, and highlighted the star's curves.

Charli added an Edie Parker clutch to her style along with Vivienne Westwood jewels, and wore her hair in her signature messy curled locks.

A bold red lip and intense smoky eyes topped off the British singer's look for the event.
