All hail Prince Louis!

The newest addition to the Royal Family of England made his official debut in these photos released by Prince William and Duchess Kate Middleton by Kensington Palace.

The little bundle of joy is welcomed by his sister Princess Charlotte, 3, and brother Prince George, 4. Apparently it was Kate showing off her photographer skills as she snapped a pic of her baby boy when he was just three days old. Loui was born April 23 at St. Mary's Hospital in London.
