The Bella of the Ball! Michelle Obama pulls out all the stops for Barack's last state dinner as she welcomes a VERY impressed Italian prime minister in a stunning custom-made Versace gown

It was a 'bittersweet moment' for the Obamas on Tuesday as they welcomed Italian Prime Minister Matteo Renzi and his wife for an official visit and the final state dinner of his time in office. With herald trumpets and a full dose of pomp and pageantry, the arrival ceremony on the South Lawn of the White House turned into a time for nostalgia and a moment for mutual admiration between Renzi and Barack Obama who promised that they had 'saved the best for last.' And the first lady lived up to that promise with her stunning custom-made Atelier Versace dress.
