Royal Couple Delights Fans with Third Child

The world has been eagerly awaiting the arrival of the third child of Prince William and Kate Middleton, and the wait is finally over.

The Duchess of Cambridge gave birth to a healthy baby boy on St George's Day, weighing 8lb 7oz.

The proud parents were all smiles as they showed off their newborn to the world outside the Lindo wing of St Mary's Hospital in Paddington, London.

As the couple emerged from the hospital, Kate was seen staring lovingly into her son's eyes, while Prince William joked that he didn't keep the world waiting too long after Kate went into labor at around 6am before giving birth five hours later.

He also revealed that their older children, Prince George and Princess Charlotte, were delighted at the arrival of their little brother.

The couple was coy about revealing the name of their new addition, but promised that the public would find out soon enough.

The baby boy is now fifth in line to the throne, behind his grandfather Prince Charles, father Prince William, older brother Prince George, and older sister Princess Charlotte.

The royal family's newest addition was greeted by a crowd of adoring fans who had been camped outside the hospital for days in anticipation of the birth.

Prince William even gave his first royal wave to the crowd, much to their delight.

As the family headed back inside, the Duchess of Cambridge murmured to Prince William that she was worried about the baby getting cold.
