Lady Grey Jewelry's teaming up with Rogan. The Brooklyn-based brand, designed by Sabine LeGuyader and Jill Martinelli, is collaborating with the denim designer on an exclusive jewelry line. Rogan's never done jewelry, and the girls have never done denim, so we're curious to see how they Rogan-ize their rings, bangles and necklaces. Or will there be Lady Grey hardware on Rogan's clothes? And will we be seeing it at his Spring collection preview tonight? Meanwhile, when we interviewed the girls back in July, they mentioned that they're dying to be sold in Barneys. We know Julie Gilhart loves Rogan, and now Rogan loves Lady Grey, so, basically, good move girls.
