Michelle Obama and Mexico's First Lady Margarita Zavala Photo

Long week! The president hosted dignitaries from around the world while Michelle skipped down to Mexico. We saw celebrities do their famous-people work, like posing for pictures at the opera, taping reality shows, and getting pap smears in public. And then, the week ended, as it should, with a party in the desert when the Coachella Music Festival kicked off Friday.
