The entrepreneur and mom of three, 43, braved the weather to attend the 5th Jam For Janie Grammy Awards Viewing Party at the Hollywood Palladium alongside her sister Ashley Simpson Ross and her husband Evan Ross — and she did so in sexy style. Simpson wore a slinky red dress that dipped low in the front and had lace trim around the bustline and matching lace sleeves. It also had metal accent studs at her hips to bring some edge to the look. She wore a red choker to match and added a few rings to round out her jewelry. Her blonde hair was down in loose waves and she rocked a heavy smokey eye for music's biggest night. Jessica Simpson, Evan Ross and Ashlee Simpson Ross at Jam for Janie GRAMMY Awards Viewing Party.

The family posed for photos together throughout the night, and Simpson also indulged in watching the 2024 Grammys as they aired at the party. She was on her feet watching Olivia Rodrigo perform her hit single "Vampire," which she'd earned nominations for record of the year, song of the year and best pop solo performance for. Simpson was also paying rapt attention to the TVs when Taylor Swift nabbed her first award of the night for best pop vocal album for Midnights and subsequently surprised everyone by announcing a brand new album, The Tortured Poets Department, coming out April 19.
