The Duchess and the Duke have welcomed a brand new bundle of joy.

Kate Middleton and Prince William welcomed their newborn bundle of joy on May 2 and it's a girl! 

After checking in to the Lindo Wing at St. Mary's Hospital at 6:00 a.m. local time, the Duchess of Cambridge safely delivered her daughter at 8:34 a.m., with her husband by her side. The new princess weighed in at 8 lbs. 3 oz, just slightly less than her big brother, Prince George!

"Her Royal Highness and her child are both doing well," Kensington Palace said in both a statement and on Twitter. "The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall, Prince Harry and members of both families have been informed and are delighted with the news."

Now we just await the baby's girl name, which will be styled as Princess [Name] of Cambridge, she will be fourth in the line of Succession, behind her grandpa, her father and her nearly two-year-old adorable brother.

Up until giving birth, the royal couple had managed to keep the sex of baby under wraps -- though grandpa Prince Charles made his preference known! -- causing fans and avid gamblers to take bets on the new baby's gender.

England has been caught up once again in the Royal Baby craze, which first swept the nation in 2013 when the couple welcomed their first child, Prince George, who will be turning two on July 22.

Will and Kate first announced they were expecting on Sept. 8, where they revealed that the Duchess was due sometime in mid to late April. Kate ended up passing her due date by an entire week when she was finally rushed to the hospital after going into labor.

Will's younger brother left for Australia on April 26 and has an official tour of New Zealand that will keep him from meeting his new niece until the middle of May.
