WASHINGTON (MCT) — First lady Michelle Obama will lead a presidential delegation to Friday’s opening ceremony for the 2012 Summer Olympics in London, and plans to meet Queen Elizabeth II, cheer on Team USA and inspire kids to get fit during a four-day trip.

“Leading our nation’s delegation and traveling to London is truly a dream come true,” she told reporters during a conference call Monday. “If anybody had asked me when I was 10 or 11 or 20 or actually 40, whether I would be doing this, I would have bet not. Some of my fondest memories when I was young and not so young involved watching the Olympics on TV.”
