Scout Willis dazzled in a sequined mini dress alongside her eccentric sister Tallulah at the Stella McCartney x Adidas launch party on Thursday.

The daughters of Bruce Willis and Demi Moore were sure to turn heads in their sparkling ensembles at Henson Recording Studios in Los Angeles.

The budding musician Scout, 31, opted for a silver outfit with a matching cape and choker for the event.

She completed her look with a pair of nude fishnet stockings and increased her height with clear heels.

Tallulah, 29, wore a metallic gold and orange dress with a voluminous neckline that fell over her arms and down to her knees.

She paired her look with a pair of star print tights, red mules and a matching red leather handbag.

Tallulah wore her cropped hair in a tousled look and finished her outfit with a sweep of orange eyeshadow.

It comes after Scout shared a hilarious reaction to her older sister’s pregnancy news when she posted a witty story on Instagram on Friday.

The musician posted a video that mocked a spot on her face while paying tribute to her sister Rumer, 34, who announced this week that she was expecting her first child with Vista Kicks frontman Derek Richard Thomas , 28 years old.

“@rumerwillis is growing a baby and all i’m growing is this giant zit and my fan base,” Scout wrote on his excerpt.

With her hair up in a messy bun, Scout flaunts her gorgeous face as she stares into the camera.

Her complexion is generally flawless except for the large pimple near the corner of her mouth.

Scout’s cheeky Instagram story came on the heels of her pregnant sister flaunting her bump.
