William meets Obama at White House and tells President: 'I forgot to ask whether George was a boy or a girl when he was born'

The future king left his pregnant wife Kate, the Duchess of Cambridge, in New York - where the couple arrived Sunday night to a rock star welcome. Prince William - who is second in line for the English throne - will meet with Obama in the Oval Office this afternoon. The two have met before - but never on Obama's home turf. The last time the two met was in London.
