Yesterday, we brought you a fun quiz, courtesy of a fellow celebrity news site, in which you had to identify a seriously f-i-n-e celebrity piece of ass. Literally.
If you haven't tested your skillz on that one yet, follow the fine ass link. We won't spoil the results by telling you who those seriously ultry buns belong to.
Today's trivia is a bit more straightforwardâ€¦ and inspired by the t-shirt donned by the youngster in question. We ask you, fans, who is the person in the celebrity photo below?
Who is this mystery celebrity out for a stroll and trying to keep a low profile? We think you can get this easy one. Follow the jump to find out.
It's Rumer Willis, of course!
Asking the question on all our minds, Bruce Willisâ€˜ eldest daughter went majorly incognito as she headed out for a shopping excursion in Bel Air Tuesday.
Surprisingly, neither of her BFFs, Hayden Panettiere or Lindsay Lohan (seen with Rumer Willis above) were to be found in the mystery picture we showed you first.
