Sweden's Princess Estelle knows how to have a good time and the latest official royal photo is here to prove it. The three-year-old princess is seen dancing as her parents, Crown Princess Victoria and Prince Daniel, stand smiling behind her.

The photo of the young family was taken during the Nobel Prize ceremony last December but was released on 25 September by the Swedish Royal Court. The regal photo shows the heir to the throne wearing a black and navy blue gown along with the Fringe Baden tiara and a necklace that belonged to her beloved late aunt Princess Lilian, Hello! Magazine reported.

Prince Daniel stands next to his wife in a dapper black tuxedo as they both hold the hands of their playful daughter, then 22-months-old. According to Hello! the photo was taken before the royal couple attended a dinner hosted by King Carl Gustaf and Queen Silvia in honour of the Nobel Prize winners.

The Swedish royal family is set to add yet another member to its expanding family. As previously reported by IBTimes UK, on 4 September it was announced that Victoria and Daniel will be making their daughter a big sister. The royal couple made the joyous announcement in a statement posted on the family's official Facebook page.

"Their Royal Highnesses Crown Princess Victoria and Prince Daniel are happy to announce that The Crown Princess is expecting their second child. The birth is expected to take place in March of 2016," the statement read. The baby's birth will come just months after the birth of Prince Nicolas, the second child of Victoria's younger sister, Princess Madeleine.

The pregnant Crown Princess will join her royal siblings during the young prince's christening. Prince Nicolas, who was born a day after his uncle Prince Carl Philip's wedding to Princess Sofia on 15 June, will be christened on 11 October at the Royal Chapel in Stockholm's Drottningholm Palace.
