Scout Willis goes completely topless as male alter ego on Halloween

Scout Willis, the daughter of Demi Moore and Bruce Willis, got a lot of people talking with her completely topless Halloween costume over the weekend.

The 25-year-old dressed up as her male alter ego, Scott, for a party in Los Angeles, and she didn't wear a shirt for part of the night.

Instead of a shirt, Willis opted for some chest hair to barely cover her breasts.

"Scott rides again," she captioned her head-turning photo on Instagram, seemingly alluding to the name of her alter ego. "Resist him if you dare."

In another photo, she "met" Weird Al Yankovic. This time, she was wearing a shirt -- but it was an unbuttoned short-sleeve shirt that still showed off her uncovered chest.

In addition to her (presumably) fake chest hair, Willis also rocked a beard, underarm hair, a necklace and dad jeans.

Scout Willis wasn't the only celebrity to rock a racy Halloween costume this year, of course. Check out the gallery below to see more sexy costumes from Lindsay Lohan, Kylie Jenner, Kourtney Kardashian and more stars:
