Introducing, Princess Adrienne!
The royal baby was born on Friday at Stockholm’s Danderyd Hospital.
“Leonore and Nicolas welcoming their little sister home,” she captioned the sweet snap.
Adrienne’s grandfather, King Carl XVI Gustaf, announced the newborn princess’s name and title at a specially convened cabinet meeting on Monday.
At noon, artillery troops celebrated Princess Adrienne’s birth at five locations around Sweden as they fired 21-gun salutes
For now, the royals are settling into life as a family of five in their home in Stockholm, although they are based full-time in London. Madeleine traveled home to Stockholm last month so she could have the baby in Sweden.
“It’s great living in London, London is easy to like,” Princess Madeleine said in the STV documentary Året med kungafamiljen. “There are lots of parks, people are friendly, it suits us.”
But, she said, “of course we miss our family and all our friends, Sweden’s countryside, the food — it’s a long list.”

Princess Adrienne, who is tenth in line to the Swedish throne, is the newest addition to the Swedish royal family, which has experienced a baby boom recently. Madeleine’s siblings Princess Victoria and Prince Carl Philip have both welcomed young children into the family in the past few years.
“We are delighted with the new addition to our family,” said O’Neill, who was at Danderyd Hospital in Stockholm throughout his wife’s labor.
“Leonore and Nicolas have their long-awaited sibling,” he said in a statement released by the palace. “They can’t wait to meet their new baby sister.”
The proud parents shared the first photo of their new baby princess hours after her birth with a sweet snap taken by O’Neill at the hospital.
