Prince William and Kate Middleton Show off Royal Baby Boy

Britain's Prince William and Kate, Duchess of Cambridge hold the Prince of Cambridge, July 23, 2013, as they pose for photographers outside St. Mary's Hospital.

The world has gotten its much-anticipated first glimpse of Prince William and Kate Middleton's new royal baby boy.

In line with royal tradition, the Duke and Duchess of Cambridge stepped out of the doors of St. Mary's Hospital's Lindo Wing in London today to pose for photographs amid the wild cheers of the crowd gathered outside.

A radiant Kate held the newborn in her arms. The day-old baby was swaddled in a white blanket and poked his hand out, as if to greet the world...

Kate wore a baby-blue polka dot dress with her long brown hair flowing around her shoulders.

The new mom then handed the 8-pound, 6-ounce baby boy to his beaming father.

"He's got a good pair of lungs. That's for sure," William told the crowd. " He's a big boy. He's quite heavy. We're still working on a name, so we'll have that as soon as we can."

"It's the first time we've seen him, really, so we're having a proper chance to catch up," a smiling William said.

"It's very emotional," Kate said. "It's such a special time. I think any parent will know what this feeling feels like."

"He's got her looks, thankfully," William joked.

Kate quickly laughed and responded, "No, no, no."

So so happy for them...Cheers!!!
