Pregnant Crown Princess Victoria of Sweden joins European royals in Norway

Hosting the event was Crown Prince Haakon of Norway along with his wife Crown Princess Mette-Marit, and their children, Princess Ingrid and Prince Sverre. Mother-to-be Crown Princess Victoria of Sweden, whose husband Prince Daniel was unable to attend due to a cold, was radiant in the group shot, which was shared on the Swedish Royal Palace's official Facebook page.

Princess Estelle's godmother, Crown Princess Mary of Denmark, who was no doubt overjoyed to hear of her friend Victoria's pregnancy news recently, was also on hand, along with husband Prince Frederik and their four children. Also attending were Luxembourg's Hereditary Grand Duke Guillaume and his wife, Hereditary Grand Duchess Stéphanie.

The reunion photo is reminiscent of one released by then Crown Prince Willem-Alexander of the Netherlands and wife Queen Maxima when they hosted a similar party not long before he became king. This has resulted in some talk that Prince Haakon's father, 78-year-old King Harald, may be considering stepping down, and that the Crown Prince is gearing up to become Norway's next monarch.

It's only speculation, however. The Norwegian king has previously referred to his postion as "an oath for life", so it's unlikely he'll be heading to retirement anytime soon.
