Demi Moore's newly-single daughter Rumer Willis exudes confidence in corset dress

Rumer Willis was an ethereal beauty in a chocolate brown goddess dress at the amfAR Gala in Venice on Sunday night.

The newly-single daughter of Demi Moore and Bruce Willis , who confirmed the end of her relationship with Derek Richard Thoma s 16 months after the birth of their daughter, captivated the spotlight at the charity gala.

The mother-of-one, 36, revealed she had separated from her long-term partner on her Instagram Stories, where she made the revelation in an Ask Me Anything "uncensored" post.

Responding to the question "Are you and Derek still a couple?", she broke the news to her fans. "Nope," she said. "I am single momming it and co-parenting."

Despite her recent heartbreak, Rumer exuded confidence as she attended the star-studded soirée at Hangar Nicelli in Venice, Italy.

Rumer's platinum blonde hair couldn't be more different from her mom's famous raven locks in color, but in length, the mother-daughter duo both sport waist-length locks.

For makeup, the Once Upon A Time In Hollywood actress rocked an edgy smokey eye and nude lips to draw attention to her striking features.
