The first lady caused a shrieking frenzy among the 11-17-year old students at the Elizabeth Garrett Anderson Language School. There she explained why being smart is cool and even shared a little girl talk about her courtship with her husband, President Obama.
"By getting a good education you too can create your own destiny. I never cut class. I like being smart. I thought being smart was the coolest thing in the world," she said, echoing remarks she has made to students in Washington D.C. "You are the women that will build the world as it should be and that's why a good education is so important."
Yesterday, she and the president paid a visit to Buckingham Palace to meet with Queen Elizabeth II. The Obamas presented the queen with a gift of an inscribed video iPod, with preloaded songs, and a rare musical songbook signed by U.S. composer Richard Rodgers.
And like any good fashionista, the first lady did change her outfit from earlier in the day for the meeting with the queen.
Obama may not be their first lady, but many women of color in Britain find her inspirational, including one who told ABC News that she's inspired to achieve greater things by seeing the first lady's strength.
Later this week, Michelle Obama will attend events with other NATO spouses during the summit in France.
