The 45-year-old first lady who appeared on the late night chat show via satellite was forced to speak about her husband's likes, dislikes and flaws in the 'Ten @ Ten' segment of the programme where Leno asks the guests ten rapid fire questions.
To the question if Barack Obama, would prefer watching his favourite baseball team, the Chicago White Sox, win the World Series to achieving world peace, Michelle replied, "That's a tough one and I think if you would ask him, he'd say he'd probably prefer world peace but he wouldn't mind the World Series bit too. But I think he'd choose world peace."
The best of all answers came when the chat show host forced her to spill some beans on the president's most annoying habit. Mrs Obama responded to this saying, "Ooh. We don't have enough time!"
