They looked like "a normal couple" as they left the hospital, one bystander said.
Of course, most normal couples don't have a crowd of reporters, photographers and random well-wishers waiting for them to show off their new baby.
Prince William and Catherine, the Duchess of Cambridge, emerged from St. Mary's Hospital in London on Tuesday evening to give the public its first view of the new heir to the British throne, joking that the still-unnamed boy had more hair than his father. Catherine and William took turns holding the child, wrapped in a cream-colored blanket, as they waved to well-wishers outside.
The couple is "still working on a name," William said, "so we'll have that as soon as we can." But he added, "He's got her looks, thankfully."
The prince has already changed his first diaper, the couple told reporters.
"It's very emotional. It's such a special time," Catherine said.
The couple left the hospital Tuesday evening, with William carrying the boy out in a car seat and installing him in the back of a black SUV. Then he got behind the wheel for the trip to their residence at Kensington Palace.
On their way out, they walked out down the same steps where Diana, Princess of Wales, and Prince Charles gave the world its first look at Prince William 31 years ago.
"It was so exciting. It was fantastic," said Eliza Wells, one of those gathered outside the hospital. "The crowd erupted, because everyone's been waiting so long for it."
William and Catherine "both seemed very relaxed, even with the press there and the crowd," Wells said. "They just seemed like a normal couple."
Shortly before the departure, Charles stopped by for a brief visit with his first grandchild, accompanied by his wife, Camilla, the Duchess of Cornwall. He told reporters it was "marvelous."
And Catherine's parents, Carole and Michael Middleton, visited earlier, with Carole Middleton telling reporters the royal baby is "absolutely beautiful."
She said both mother and baby are doing "really well" and that she and her husband were "so thrilled" at being grandparents.
Bells, gun salutes
The 8-pound, 6-ounce boy was born Monday afternoon. He's third in line, behind Charles and William, for the British throne now held by his great-grandmother, Queen Elizabeth II.
Tuesday, London echoed with the sound of cannonades and music to mark the birth.
Guardsmen at Buckingham Palace, the queen's residence, played the Cliff Richard song "Congratulations" at the Changing of the Guard. The military ceremony, much beloved by tourists, involves a new guard exchanging duty with the old guard in the palace forecourt.
The King's Troop Royal Horse Artillery in Green Park fired 41 shots in tribute to the boy, while the Honorable Artillery Company at the Tower of London fired 62 rounds.
At the same time the bells of Westminster Abbey, where William and Catherine were married in April 2011, began to peal, in keeping with royal tradition, and were set to continue for more than three hours.
The news of the boy's birth, announced about four hours after the event Monday, prompted cheers and celebration among the crowds of well-wishers outside Buckingham Palace. At least one group of well-wishers brought flowers, champagne and a card for the Duke and Duchess of Cambridge.
Social media networks were also abuzz with the news, which made headlines around the world.
'We could not be happier'
The new parents spent some time with their baby before calling family members -- starting with the queen -- to announce the birth, a Kensington Palace source told CNN royal correspondent Max Foster.
"We could not be happier," said Prince William, according to the Kensington Palace source.
Prince William remained at Catherine's side throughout the labor, and the baby was born naturally. An official bulletin was placed on a gilded easel outside Buckingham Palace.
