There's no doubt this lead singer knows how to inject a little rock ‘n' roll flair into an outfit and she certainly proves that point at the AMAs, layering an edgy chic embellished Balmain jacket over a bra (also by the designer) with curve-hugging leather leggings. D'Orsay heels, plus a diamond, pearl and platinum cross and chain necklace from Neil Lane complete her unique red carpet look.
