>> THE MODELIZER —Ubah Hassan, the Somalian model who first appeared the historic issue of Vogue Italia last year, has become a Ralph Lauren favorite.  She closed out his Spring 2009 show last September and joins Valentina Zelyaeva in the label's Spring 2009 campaign, which is big for two reasons — first, because Valentina's Ralph exclusive helped catapult her onto the list of top-earning models for 2008, and second, because we all know what a little Ralph love can do for a model — think Tyson Beckford.
