Celebrities on this week's red carpets proved that the neckline can make or break any outfit.

Demi Lovato attended the premiere of YouTube's "Demi Lovato: Simply Complicated" in a strapless gown with a deep-V plunging neckline and sky-high slit. The singer paired the sexy look with stilettos of the same hue. She kept the rest of her look simple, pulling her brunette tresses back in an updo while adorning herself with sparkly jewels.

For the premiere of "Faces Places," Jennifer Lawrence dazzled in a semi-sheer cream-hued gown with a low neckline. To add a bit of an edge to the angelic look, she painted her lips in a bold and bright red color, while adding texture to her blonde locks with a wavy style.

Meanwhile, Elizabeth Hurley was a bombshell in pink at a Breast Cancer Awareness month event. The actress stunned in a form-fitting hot pink look with floral detailing on the neckline.

Paris HIlton, Emmy Rossum and Keke Palmer also made our list of the best red carpet looks of the week. Check out the slideshow above for more!
