Today, People StyleWatch asked, "What Has Nicole Richie and Gwyneth Paltrow Teaming Up?" And, perhaps surprisingly, the answer is not something to do with macrobiotic food, or a high-stakes game of bridge.

The pair, whose partnership grew out of a "personal friendship" (as opposed to an impersonal one), believe the purse is "the perfect piece to complement everyone's wardrobe."
