But while sources say the tot's first night was "peaceful", new dad Harry had another thing to say about his "absolutely to die for" son!
WATCH this video for his hilarious revelation:
News of the royal baby comes as it emerged Meghan's hopes of a home birth at Frogmore were dashed when the overdue Duchess was secretly whisked to a London Hospital by Prince Harry and their Scotland Yard Security detail.
According to Daily Mail, Meghan was taken to the American-owned Portland Hospital, the same facility where Sarah Ferguson gave birth to her daughters Princesses Beatrice and Eugenie.
While previous reports alleged the Sussexes' had chosen free-of-charge public hospital Frimley Park in Surrey, deliveries at the Portland cost upwards of $28,000 AUD making it more expensive than the ultra-exclusive Lindo Wing of St Mary's Hospital where Kate Middleton welcomed her three children, Prince George, Princess Charlotte and Prince Louis.
Just hours after the birth, a beaming Harry gave an impromptu press conference declaring his wife had safely delivered "a very healthy baby boy".
Harry, 34, gushed about becoming a father calling it "the most amazing experience I could ever have possibly imagined" and praised women for doing something "beyond comprehension".
British bookmakers continue to take bets on the name of the Sussexes' first born son, with Alexander, James and Arthur leading the field.
Spencer, a more unusual moniker, is also a strong contender as fans predict the couple will choose the name in honour of the maiden name of Harry's late mother, Princess Diana.
