Michelle Obama on Letterman: This isn't Oprah

America's First Lady, Michelle Obama, was speaking on Monday to US talk show host David Letterman about her family and how she and husband Barack have been raising their children.

It was Michelle Obama's first appearance on The Late Show With David Letterman and as the interview became more personal she joked: "Don't make me cry, this isn't Oprah. It's supposed to be Letterman. What's up? Where are the laughs?"
