Michelle and Barack Obama gave South Korean president Lee Myung-bak and First Lady Kim Yoon-ok a warm welcome to the White House on a rainy evening last night. For the double-date night, Michelle wore a purple creation by Korean-American designer Doo-Ri Chung. The menu, a festive "Fall harvest," included squash and honey from the White House garden and Korean and American pears in the dessert. The Obamas are becoming pros at hosting official galas, as this is their fifth state dinner. Since he became president, Barack and his wife have welcomed dignitaries from Germany, China, Mexico, and India. See sweet photos from the latest now!
