Ashlee was there to support her older sister as she promoted the Jessica Simpson Collection. Aww!
The blonde babes kept it pretty casual in their respective outfits, with Jessica rocking distressed jeans and a hot pink blazer, while Ashlee went the darker route in black tights and black sweater dress with printed hem.
The younger Simpson accessorized with an extra-long Chanel necklace.
Though she kept her belly covered, it's obvi that Jessica has lost a ton of her baby weight.
We can't wait to see her hot post-baby bod in a fashion spread ASAP!
