Valentino has always been a huge name in the fashion world. But this year (and late 2011) the designer has become quite popular among young starlets. Everyone from the young and innocent Elle Fanning, to the dark and edgy Rooney has been donning Valentino gowns on the red carpet. Just about every look from the Spring 2012 RTW Collection has been worn at least once by a celeb. Just recently Cameron Diaz was spotted at Milan Fashion Week wearing a lwd from the popular collection. While Jessica Biel wore a Valentino gown back in December to the 'New Year's Eve' movie premiere.
