Just hours after giving birth, Kate Middleton, the Duchess of Cambridge, looked stunning as she greeted crowds while holding her newborn son. She wore a red dress with a lacy Peter Pan collar, and also sported high heels. She paused outside St. Mary's Hospital in London, with her husband, Prince William. The mother of three gave birth at 11 a.m. local time. A name has not been announced for the newest royal baby, who weighed 8 pounds and 7 ounces.
