Princess Sofia and Prince Carl Philip of Sweden have shared brand-new pictures of their baby girl, Princess Ines Marie Lilian Silvia.

The Swedish royals welcomed their fourth child - and only daughter - into the world on Friday, February 7.

The first picture, which was shared to Instagram, shows the newborn sleeping whilst be held by her three older brothers, Prince Alexander, 8, Prince Gabriel, 7, and three-year-old Prince Julian. The second image shows Julian sweetly kissing his little sister's forehead.

Taking to Instagram to upload the sweet pictures, the caption read: "It turned out to be a perfect little quartet. Big and warm thanks for all the nice congratulations to our little Ines."

Just weeks after welcoming his second daughter, Princess Beatrice's husband Edoardo Mapelli Mozzi took to the comment section to congratulate the couple on the birth of their first daughter.

The new pictures have been released shortly after her grandfather, King Carl of Sweden, caused confusion over the newborn's name.

As well as sharing that the newborn would be known as Princess Inse, he also shared her middle names in the wrong order. He instead wrote, 'Silvia Marie Lilian'.

The Swedish King - who is known to have dyslexia - later issued an apology via the royal court. They told Swedish Magazine Svensk Damtidning: "The King is very sorry that he said the wrong name.

"The reason he said the wrong name is that the names were kept secret until just before the council, even from the King."

Ines' name has roots in a number of languages, and means 'pure', 'chaste' and 'holy'. The baby girl's middle names are a tribute to her grandmother Queen Silvia, and Princess Sofia's mother, Marie Hellqvist.

The birth of Ines - who is King Carl Gustaf and Queen Silvia's ninth grandchild - was annouced shortly after. A statement confirming her birth was accompanied by a sweet picture of the adorable newborn.

Fans couldn't help but share their excitement for the new parents, with one fan writing, "Adorable! Congratulations on the little Princess!"

Another penned. 'So sweet', whilst a third shared: "Such a pretty little Ines! Congratulations to the whole family."
