Lady Gaga went for Hollywood glamor in her black, form-fitting Alexander McQueen gown but it was her necklace that stole the show. That was a $30million 128.54 carat Tiffany diamond hanging around her neck. (Guards lurked behind her but were kept off camera.) And the last time we had a peek at the jewel was when worn by Audrey Hepburn in her promotional shots for ‘Breakfast At Tiffany’s.’
