PRINCE WILLIAM and his wife KATE debuted their new baby yesterday on the steps of St. Mary's Hospital in London.  He still doesn't have a name, by the way. William told reporters 'We are still working on a name, so we will have that as soon as we can.  But it's the first time we've seen him really.'

Asked which parent the child resembles, William said, 'He's got her looks, thankfully.'  He added the kid has, 'way more' hair than he does. 'He's got a good pair of lungs on him, that's for sure.  He's a big boy . . . he's quite heavy.'

Kate called the experience 'very emotional,' adding,'It's a moment that any parent having just given birth will know what this feeling feels like.'
