Michelle Obama to Philly for mayors' conference

Michelle Obama appears in Philadelphia Wednesday to hobnob with many of the country's top municipal officials.

With the U.S. Conference of Mayors in town (led by the organization’s president, Michael Nutter), the First Lady plans to announce new efforts in her “Let’s Move” inititative to combat childhood obesity.

The event is scheduled to begin shortly before noon at the Lenfest Police Athletic Club in the city’s Hunting Park section.

A raft of prominent city chief execs are scheduled to attend, including Newark mayor Cory Booker, New Orleans mayor Mitch Landrieu, Nashville mayor Karl Dean and Charleston mayor Joe Riley.

It’s been a big week in the spotlight for Mrs. Obama, and Tuesday’s not even over.

A video love letter from Beyonce to the First Lady was released yesterday on YouTube. Later in the day, a “Kiss Cam” camera caught the president planting a smooch on his missus at a Team USA basketball exhibition game in Washington.

Here's a link to the Beyonce video.

And here's the "Kiss Cam" shot.
