First Photo! Kate Middleton and Prince William Debut the Prince of Cambridge

Introducing the Prince of Cambridge!

As expected, Kate Middleton and Prince William debuted their son outside of St. Mary's Hospital on Tuesday evening in London.

Both Kate and Wills fittingly wore baby blue while making their first public appearance since Middleton gave birth on Monday. Kate donned a bespoke cornflower blue crêpe de chine dress by British designer, Jenny Packham.

The Duchess of Cambridge emerged with her son securely in her arms as she and her husband exited the hospital. Middleton, 31, then handed her newborn baby boy over to the Duke of Cambridge where he remained safely in dad's arms as they answered a few questions from the awaiting media outside.

"It's very emotional and such a special time," Kate exclaimed. "Any parent knows what this feeling feels like."

"He's got way more [hair] than me, thank God," William, 31, joked adding, "He's got her looks thankfully" and "a good set of lungs."

"I'll remind him of his tardiness when he's a bit older," Prince William also quipped, clearly referencing The Great Kate Wait (the media has been set up outside the hospital since July 1).

The Prince of Cambridge does not yet have a name, with Prince William admitting they are "still working" on it.

After addressing the media, Kate, Prince William, and their son headed to Kensington Palace to their newly refurbished apartment with William behind the wheel (and security detail following closely, of course).

The Duchess of Cambridge, 31, "safely delivered" a baby boy 4:24 p.m. local time on July 22, 2013.

Princess Diana and Prince Charles introduced Prince William to the world on the exact same steps in June 1982, just one day after she gave birth, as well.

And here's an interesting fun fact: both Kate and Princess Diana wore polka dots for their iconic debut.
