New Photos of Prince George Released by Kensington Palace

Kensington Palace has released three new photos of Prince George. Taken in the Kensington Palace courtyard in November, the pictures show the third in line to the crown increasingly resembling his father.

In each of the three photos, Prince George, dressed in a sweater adorned with the Queens Guards in traditional bearskin hats, has different expressions.

George will be joined by a sibling in April next year.

Prince William joked with President Obama they want the sex of their unborn baby to be a surprise, and when George was born he hadn't realized initially whether the baby was a boy or girl.

'We want a surprise. When George was born, I forgot to work out whether it was a boy or a girl. The excitement of the event and everything else was just chaos. You are suddenly ... well actually it's a boy,' the Duke of Cambridge told the president.

Will and Kate are just coming off a wildly successful tour of the United States. They decided to leave Prince George in London while they made the 48-hour trip to New York and Washington, D.C., for the first time.

Americans rolled out the royal red carpet for Prince William and Princess Kate. The couple crammed in the best of the East Coast while they were here.

William made a quick trip to Washington, D.C., that included a stop at the White House.

In New York, he hit the observation deck of the Empire State Building. The couple paid their respects at the 9/11 Memorial.

The real life royalty also rubbed shoulders with American royalty -- LeBron 'King' James, 'Queen Bey' Beyonce and Jay Z at a basketball game between the Cleveland Cavaliers and Brooklyn Nets.

The couple spent their final night at the Metropolitan Museum of Art for a fundraiser celebrating the 600th anniversary of St. Andrews University, their alma mater where they met and fell in love

'One of the reasons the photographs have been released by Their Royal Highnesses is in grateful acknowledgment of the fact that their request for Prince George to grow up without intrusion from photography has been, and continues to be, honoured,' Royal sources told ABC News.

The Cambridges want George to be able to experience childhood that is as normal as possible, but they also acknowledge the great public interest in their young son.
