In one pic, the Die Hard actor, 59, is all dolled up in drag. Willis wears an orange wig with curlers and a floral printed dress, which he accessorizes with pearl jewels. Scout simply captioned the photo, "Creator of 5 daughters."
In the second post, the outspoken 22-year-old shared a picture of her father shirtless in a tub. In the shot, Bruce wears only a hat, jeans, socks and shoes. Scout wrote alongside the photo, "Man, Myth, Legend, Daddio. S/o to the one and only BW #FreeTheNipple."
Bruce's daughter with ex Demi Moore made headlines last month when she posted a photo of herself walking through New York City without a shirt, exposing her bare breasts, in an attempt to protest Instagram's no nudity policy after she'd been kicked off the social media app.
"Legal in NYC but not on @instagram," Scout captioned a pic, while adding in another, "What @instagram won't let you see. #FreeTheNipple."
On June 2, the recent Brown graduate explained her actions via a column on Jane Pratt's lifestyle site xoJane. She wrote that she wasn't "trying to argue for mandatory toplessness, or even brainlessness," but "a woman's right to choose how she represents her body."
