Hear ye, hear ye! He's here! The newest little royal has arrived. Proud parents Prince William and Kate Middleton, a.k.a. the Duke and Duchess of Cambridge held their newborn baby boy outside of St. Mary's Hospital in London to allow the world to see the baby prince on his first day of life.

He (currently unnamed) was born this morning at 11:01 BST and weighs a healthy 8 pounds and 7 ounces. Kate looked fashionable as always in a lovely red dress with a dainty cream-colored lace collar, as she stood next to her husband and snuggled the newborn who was wrapped in a white receiving blanket with scalloped edges and a soft white knit cap to keep his head warm on this slightly windy day.

But before the happy parents introduced their newest child to the world, William was seen exiting the hospital, making his way to a waiting car and told the eager media that he would "be back in a minute." As promised, the prince promptly returned flanked by his two older children, Prince George and Princess Charlotte. It was obvious that all three were pleased as punch and super excited about the addition to their growing family. Prince William and his children were all smiles, and Princess Charlotte sweetly waved to photographers as the trio made her way to the hospital.

The royal little girl even turned back to wave once more at the media as she walked up the steps to the hospital's entrance. E! has it on good authority that George's and Charlotte's classmates and their parents were asked not to reveal the gender to the little boy, as Prince William wanted to tell his son and daughter himself when he picked them up.

The children reunited with their mother and met their baby brother, but did not greet the public for the unveiling of the littlest family member.

"Her Royal Highness The Duchess of Cambridge will be leaving St. Mary's Hospital this evening," a representative for Kensington Palace said. "The Duke and Duchess of Cambridge and their son will travel home to Kensington Palace. Prince George and Princess Charlotte have now returned to Kensington Palace. Their Royal Highnesses would like to thank all staff at the hospital for the care and treatment they have received. They would also like to thank everyone for their warm wishes."

The new baby's birthplace, St. Mary's Hospital, holds a special significance for the family. Not only were Prince George and Princess Charlotte born there, but their father Prince William was the first British royal family member to be born there himself in 1982.
