Transcript for Kate Middleton Welcomes Baby Girl
We're going to start here of course with the breaking baby news. There it is. We have a live shot of the Lindo wing of St. Mary's hospital in London where just hours ago princess Kate gave birth. And here's that announcement, the news coming via the royal Twitter account which says her royal highness, the duchess of Cambridge, was safely delivered of a daughter at 8:34 A.M. And then there was this, the baby weighs 8 pounds, three ounces. The duke was present for the birth. That's three ounces less than the birth of baby George who will be a big brother. Let's go to bob woodruff who's another of the hospital. Reporter: The familiar was also notified when this happened. I can only assume it was not by Twitter or e-mail but by regular old phone calls to the queen and the rest of the family. This place has been surrounded by hundreds of journalists and crews here waiting for this to happen. You can see there have been police guarding the street walking up and down for days out of concerns for security. I should tell you that there's been so much speculation about what else the gender going to be about this baby, but now we know. It's a girl. Prince William and princess Kate welcoming their new daughter. The whole world royally excited about prince George's baby sister. Kate admitted to the hospital at 6:00 A.M. This morning London time, finally in labor, a week past her due date. Last time around Kate gave birth after nearly ten hours of labor. The palace made the announcement on an easel at Buckingham palace and via Twitter and e-mail. This child bumps prince harry down to fifth. We all remember that day nearly two years ago when we first set eyes on prince George. He's got a good pair of lungs on him, that's for sure. He's a big boy, quite heavy. He's got her looks thankfully. It's such a special time. I think any parent having probably sort of knows what this feeling feels like. Very special. Reporter: No word on whether prince George will make an appearance where Kate has given birth. If history is an indication, his father visited princess Diana and a newborn harry nearly 30 years ago. The boy must take an pra internet and unpaid leave through June 1st. Kate is expected to take a longer maternity leave than last time. Now, the next big piece of news we're waiting for is what's going to be the name of this adorable little girl. We don't know that yet but certainly a lot of people are speculating and certainly the country is very excited and very happy that this is a little girl. Of course Kate and William already have a son and now they got a little girl as well. Paula. One of each. Bob, thank you so much.
