Wednesday's 4th Annual White Ribbon Alliance dinner hosted a number of A-List looks, including Naomi Watts' sleek "lob," Natalia Vodianova's romantic waves, and Jessica Alba's chic chignon.

It seems that Ginger Spice (a.k.a. Geri Halliwell) and Rumer Willis (the eldest of Demi & Bruce's clan) have decided to swap their signature shades ...

Geri's been everything from blonde to flaming red, but this is the first time I've seen her as a brunette. I'm not sure if she wants to be taken seriously as a writer (?) or just craves a change for fall, but I'm not minding this new hue on the former pop star. The color itself needs to be adjusted to look more natural (it's a bit wiglike at the moment), but the overall effect is positive: She looks younger, and her light eyes just pop.

Rumer, on the other hand, looks a little washed out, and that bright red bob does nothing for her face shape or features. I'd love to see her in a rich cocoa color, something between her usual jet-black and this new, Ashlee Simpson–inspired do.

Whose latest incarnation do you like more, Rumer's or Ginger's?
