Billie Eilish was one of the many A-listers in attendance at the LACMA Art+Film Gala at the Los Angeles County Museum of Art on Saturday, November 4.
Alongside the likes of Salma Hayek, Jennifer Lopez and Ben Affleck, Keanu Reeves, Eva Longoria and more, the 21-year-old singer-songwriter shined in her own right.
As a Gucci ambassador herself, she was covered in the brand from head to toe for the outing, opting for all black all the way in her oversized tracksuit.
She wore a jacket and track pants, emblazoned all over in the brand logo, which she'd paired with boots, a small chain bag, and a headscarf over her shock of black and red hair, plus a pair of tiny sunglasses.
However, Billie upped the ante on her look by adding a glamorous accessory in the form of a tiny diamond-encrusted grill on her brilliantly white teeth, flashing it for the camera with big smiles.
Billie, in fact, was one of the hosts of the affair as the brand's newest ambassador for their line of vegan apparel and accessories, and spoke with Vogue about starring in their latest campaign.

Billie was dressed in style for her appearance at the LACMA Gala last year as well, dressed in Gucci sleepwear, but made headlines for her date that night.

That night, exactly one year ago now, also happened to be her red carpet debut with then-boyfriend Jesse Rutherford, after they'd sparked dating rumors a month prior.
