Siobhan Magnus wears Betsey Johnson Striped Organza Dress on American Idol top 12 If you missed tonights American Idol top 12 preform you missed seeing Siobhan Magnus and her Rolling Stones "paint it black" top performance as well as the super cute Betsey Johnson Striped Organza Dress in Black. AMAZING! All the judges including Ellen and Simon Cowell talked about how great she looked. BETSEY JOHNSON shines again this time on American Idol. Now if I could only get a peak of Crystal Bowersox in a Betsey.. I love her the most and her in A Betsey would so make my day WHooo hooo. http://www.youtube.com/watch?v=r9OPQdoXP3k
