Here's a fun rumor as heard on the campaign trail (that's fashion, not politics, in case you're wondering): Scarlett Johansson won't be involved with Reebok anymore, and instead, the brand is actively courting more celebrity involvement from other red carpet babes. We really liked the heart-laden last collection made by Scarlett for the brand - inspired, apparently, by vintage shopping with the actress - but we can think of a few other women who are sporty, confident, and could be cool replacements. We're thinking Gwen Stefani, Jessica Biel (as much as we don't really love her), and especially Rihanna could do the honors of representing strong, sexy girls around the world. And fortunately, we heard from an insider that one of those women is indeed being considered for an upcoming partnership. Hmmm... !!!
