Hayden Panettiere, Rumer Willis Paint the Town Yellow!

We're talking about Hayden Panettiere and Rumer Willis.

They're, like, BFFs for life, which is probably a good thing, even though we make fun of them. Hey, either one could be friends with Lindsay Lohan.

Maybe it's because summer is right around the corner. Maybe it's because they want to show the world what close friends they are. Whatever their reason, they were feeling yellow. Okay, we're moving on now.

Hayden Panettiere and her weird BFF shopped around Beverly Hills Wednesday, toting around some ginormous matching handbags and goggle sunglasses.

Let's just say that while we think Hayden is the finest underage thing under the sun, she could still use some fashion tips from Lauren Conrad.

Rumer, for her part, was sporting a perky and more Demi-Moore-ish haircut than we've seen in the past. She should really get Tallulah Willis to come hang out.

That's her mom. While Rumer still looks kinda weird, we have to prefer this look to the ones sported in the last two pictures we've posted of her with Hayden, in which Willis closely resembles Clark Kent and Marilyn Manson.

On the sidewalk, Rumer Willis and Hayden Panettiere were nearly toppled by the weight of their purses, but they managed to stay on their feet, and even managed to thrown in some giggles for celebrity gossip gawkers.

How nice!
