Rumer Willis (or Scout Willis) is a Half-Nude Dunce

The oldest daughter of Bruce Willis and Demi Moore, Rumer Willis, wears a dunce hat, a neck and back brace, and little else on the set of the Untitled Anna Faris Project.

Mmm. Rumer Willis almost sort of nude. In a dunce cap. That's ... hot?

Several people commenting on Just Jared, which first brought us these Rumer pics, claim that it's not Rumer, but rather her younger sister, Scout Willis.

We will give theme this: It doesn't much look like Rumer. But with Scout Willis being like 12, and Rumer signed to work on the movie, we're gonna go and say it's her.

As for the film, little is known. IMDB says the movie is about a recently sacked pin-up girl (Faris) who signs up to be the new house mother at UCLA's nerdiest sorority.

Wikipedia claims Faris is acting and producing in House Bunnies, a film with Adam Sandler's Happy Madison Productions, about a retired Playboy bunny.

Former American Idol runner-up Katharine McPhee has also signed up for this movie. We'd love to see McPhee in this outfit wearing a dunce cap too (it wouldn't be a huge stretch). Or even less, if you know what we're talking about.

We're talking about a nude Katharine McPhee, people.
