The "Truth Hurts" singer walked the carpet carrying a minuscule beige flap-style handbag that appeared to measure only an inch or so wide. Lizzo said the tiny purse was a custom Valentino creation, one of only three in existence, and joked that she squeezed a flask of tequila into the bag.
Lizzo also wore a bright orange, one-shoulder ruffled dress and beige heels.
One of the year's breakout stars, she's nominated for New Artist of the Year, Favorite Female Artist - Soul/R&B and Favorite Song - Soul/R&B for "Juice." Her competition for New Artist of the Year includes Luke Combs, Billie Eilish, Lil Nas X and Ella Mai.
She's also set to perform during Sunday night's telecast on ABC.
