Princess Estelle dances about in formal photo

Princess Estelle added a playful touch to a very regal picture of her mother, the future queen of Sweden. Crown Princess Victoria and husband Prince Daniel, who wed in a fairytale wedding in 2010, were dressed in full royal regalia for the photo, taken at the time of the Nobel Prize ceremony last December but released now.

In the image the heiress to the throne is wearing the magnificent Fringe Baden tiara and a necklace that belonged to her adored late aunt Princess Lilian. Even so her daughter, then 22 months, managed to steal the limelight by dancing around in what is nominally a formal portrait.

The image was taken just before the couple went in to a dinner given by Victoria's parents King Carl Gustaf and Queen Silvia in honour of prize winner. Since then there have been so many exciting developments for the family.

The crown princess has announced the happy news that the couple are expecting a brother or sister for Estelle. She's since been seen looking well, most notably at a gathering of her peers, including the crown princes of Norway and Denmark, during a country weekend.

Victoria's sister Princess Madeleine has had her second child, Prince Nicolas who will be christened on 11 October in Drottningholm Palace, in the outskirts of Stockholm. It is the same place where his big sister Princess Leonore, who is now 19 months old, was also baptised last year. The king and queen will clearly be happy to have all their grandchildren together again.

For the ceremony to be conducted by Sweden's first female archbishop Antje Jackelen, Madeleine and her husband Chris O'Neill will travel back from London, where they are based due to his career in financial services.

Of course, the other lovely news for the Swedish royals was the wedding of the princesses' brother Carl Philip. He married Sofia Hellqvist in another stunning royal celebration in the Royal Chapel Stockholm.
