Michelle Obama stuns at the White House state dinner

President Obama hosted Singapore's Prime Minister Lee Hsien Loong and his wife, Ho Ching at the 12th state dinner Tuesday night in Washington. The black-tie affair – called by the White House a 'celebration of summer bounty' – marked the 50th anniversary of bilateral relations between the U.S. and the city-state, which Obama referred to as an anchor for the U.S. presence in Southeast Asia.
