Princess Rosario of Bulgaria and her husband Prince Kyril are also good friends of the Norwegian crown prince couple, and the royal families are related.
In addition to the sponsors, several other royal guests attended the baptism, including Denmark's Queen Margrethe, the Danish crown prince couple and Crown Princess Victoria of Sweden.
- The whole nation wishes good luck and thank the God of Life for the hope represented by the little one, Bishop Kvarme said.
The Bishop added that the first pictures of the little Prince Sverre Magnus showed us a face with eyes that were wide awake, and an open face.
- It is fascinating to look into a baby's expecting and scrutinizing gaze. What will these eyes be experiencing and see in the days and years ahead, Kvarme said.
Crown Princess Mette-Marit red the lesson from the Gospel of Matthew, and Kari Bremnes sang 'Et lite barn som kommer' (A little Child a'coming), a song she had written for the Prince's baptism.
Sverre Magnus' baptismal dress was made by The Prince's great grandmother, Princess Ingeborg in 1920.
Outside, the snow-clad capital was bathed in beautiful sunshine, inside the Royal Chapel was decorated with spring flowers in blue, green, white and off white.
