The royal baby made his first public appearance Tuesday as the world watched.
Duchess Kate and Prince William, Duke of Cambridge, walked out of central London's St. Mary's Hospital around 11:15 a.m. Arizona time with their newborn son.
He was born at 8:24 a.m. Arizona time Monday.
Kate and William were both grinning ear to ear as they waved to the hundreds of people cheering in the streets and on the bridge above.
